:mod:`codecs` --- Codec registry and base classes
=================================================
.. module:: codecs
:synopsis: Encode and decode data and streams.

This module defines base classes for standard Python codecs (encoders and
decoders) and provides access to the internal Python codec registry which
manages the codec and error handling lookup process.
It defines the following functions:
.. function:: register(search_function)
Register a codec search function. Search functions are expected to take one
argument, the encoding name in all lower case letters, and return a
:class:`CodecInfo` object having the following attributes:
* ``name`` The name of the encoding;
* ``encode`` The stateless encoding function;
2007-08-15 11:28:22 -03:00
* ``decode`` The stateless decoding function;
2007-08-15 11:28:22 -03:00
* ``incrementalencoder`` An incremental encoder class or factory function;
* ``incrementaldecoder`` An incremental decoder class or factory function;
* ``streamwriter`` A stream writer class or factory function;
* ``streamreader`` A stream reader class or factory function.
The various functions or classes take the following arguments:
*encode* and *decode*: These must be functions or methods which have the same
2007-08-15 11:28:22 -03:00
interface as the :meth:`encode`/:meth:`decode` methods of Codec instances (see
Codec Interface). The functions/methods are expected to work in a stateless
mode.

* ``'surrogateescape'``: replace with surrogate U+DCxx, see :pep:`383`
as well as any other error handling name defined via :func:`register_error`.
2007-08-15 11:28:22 -03:00
In case a search function cannot find a given encoding, it should return
``None``.
.. function:: lookup(encoding)
Looks up the codec info in the Python codec registry and returns a
:class:`CodecInfo` object as defined above.
Encodings are first looked up in the registry's cache. If not found, the list of
registered search functions is scanned. If no :class:`CodecInfo` object is
found, a :exc:`LookupError` is raised. Otherwise, the :class:`CodecInfo` object
is stored in the cache and returned to the caller.
To simplify access to the various codecs, the module provides these additional
functions which use :func:`lookup` for the codec lookup:
.. function:: getencoder(encoding)
Look up the codec for the given encoding and return its encoder function.
Raises a :exc:`LookupError` in case the encoding cannot be found.
.. function:: getdecoder(encoding)
Look up the codec for the given encoding and return its decoder function.
Raises a :exc:`LookupError` in case the encoding cannot be found.
.. function:: getincrementalencoder(encoding)
Look up the codec for the given encoding and return its incremental encoder
class or factory function.
Raises a :exc:`LookupError` in case the encoding cannot be found or the codec
doesn't support an incremental encoder.
.. function:: getincrementaldecoder(encoding)
Look up the codec for the given encoding and return its incremental decoder
class or factory function.
Raises a :exc:`LookupError` in case the encoding cannot be found or the codec
doesn't support an incremental decoder.
.. function:: getreader(encoding)
Look up the codec for the given encoding and return its StreamReader class or
factory function.
Raises a :exc:`LookupError` in case the encoding cannot be found.
.. function:: getwriter(encoding)
Look up the codec for the given encoding and return its StreamWriter class or
factory function.
Raises a :exc:`LookupError` in case the encoding cannot be found.
.. function:: register_error(name, error_handler)
Register the error handling function *error_handler* under the name *name*.
*error_handler* will be called during encoding and decoding in case of an error,
when *name* is specified as the errors parameter.
For encoding *error_handler* will be called with a :exc:`UnicodeEncodeError`
instance, which contains information about the location of the error. The error
handler must either raise this or a different exception or return a tuple with a
replacement for the unencodable part of the input and a position where encoding
should continue. The encoder will encode the replacement and continue encoding
the original input at the specified position. Negative position values will be
treated as being relative to the end of the input string. If the resulting
position is out of bound an :exc:`IndexError` will be raised.
Decoding and translating works similar, except :exc:`UnicodeDecodeError` or
:exc:`UnicodeTranslateError` will be passed to the handler and that the
replacement from the error handler will be put into the output directly.
.. function:: lookup_error(name)
Return the error handler previously registered under the name *name*.

Implements the ``backslashreplace`` error handling (for encoding only): the
unencodable character is replaced by a backslashed escape sequence.
2007-08-15 11:28:22 -03:00
To simplify working with encoded files or stream, the module also defines these
utility functions:
.. function:: open(filename, mode[, encoding[, errors[, buffering]]])
Open an encoded file using the given *mode* and return a wrapped version

*encoding* specifies the encoding which is to be used for the file.
*errors* may be given to define the error handling. It defaults to ``'strict'``
which causes a :exc:`ValueError` to be raised in case an encoding error occurs.
*buffering* has the same meaning as for the built-in :func:`open` function. It
defaults to line buffered.
.. function:: EncodedFile(file, data_encoding, file_encoding=None, errors='strict')
2007-08-15 11:28:22 -03:00
Return a wrapped version of file which provides transparent encoding
translation.
Bytes written to the wrapped file are interpreted according to the given
*data_encoding* and then written to the original file as bytes using the
*file_encoding*.

The module also provides the following constants which are useful for reading
and writing to platform dependent files:
.. data:: BOM
BOM_BE
BOM_LE
BOM_UTF8
BOM_UTF16
BOM_UTF16_BE
BOM_UTF16_LE
BOM_UTF32
BOM_UTF32_BE
BOM_UTF32_LE
These constants define various encodings of the Unicode byte order mark (BOM)
used in UTF-16 and UTF-32 data streams to indicate the byte order used in the
stream or file and in UTF-8 as a Unicode signature. :const:`BOM_UTF16` is either
:const:`BOM_UTF16_BE` or :const:`BOM_UTF16_LE` depending on the platform's
native byte order, :const:`BOM` is an alias for :const:`BOM_UTF16`,
:const:`BOM_LE` for :const:`BOM_UTF16_LE` and :const:`BOM_BE` for
:const:`BOM_UTF16_BE`. The others represent the BOM in UTF-8 and UTF-32
encodings.

interface and can also be used to easily write your own codecs for use in
Python.
2007-08-15 11:28:22 -03:00
Each codec has to define four interfaces to make it usable as codec in Python:
stateless encoder, stateless decoder, stream reader and stream writer. The
stream reader and writers typically reuse the stateless encoder/decoder to
implement the file protocols.
The :class:`Codec` class defines the interface for stateless encoders/decoders.
To simplify and standardize error handling, the :meth:`encode` and
:meth:`decode` methods may implement different error handling schemes by
providing the *errors* string argument. The following string values are defined
and implemented by all standard Python codecs:
+-------------------------+-----------------------------------------------+
| Value | Meaning |
+=========================+===============================================+
| ``'strict'`` | Raise :exc:`UnicodeError` (or a subclass); |
| | this is the default. |
+-------------------------+-----------------------------------------------+
| ``'ignore'`` | Ignore the character and continue with the |
| | next. |
+-------------------------+-----------------------------------------------+
| ``'replace'`` | Replace with a suitable replacement |
| | character; Python will use the official |
| | U+FFFD REPLACEMENT CHARACTER for the built-in |
| | Unicode codecs on decoding and '?' on |
| | encoding. |
+-------------------------+-----------------------------------------------+
| ``'xmlcharrefreplace'`` | Replace with the appropriate XML character |
| | reference (only for encoding). |
+-------------------------+-----------------------------------------------+
| ``'backslashreplace'`` | Replace with backslashed escape sequences |
| | (only for encoding). |
+-------------------------+-----------------------------------------------+
2009-06-29 03:35:26 -03:00
| ``'surrogateescape'`` | Replace byte with surrogate U+DCxx, as defined|
| | in :pep:`383`. |
+-------------------------+-----------------------------------------------+
2007-08-15 11:28:22 -03:00
In addition, the following error handlers are specific to a single codec:
+-------------------+---------+-------------------------------------------+
| Value | Codec | Meaning |
+===================+=========+===========================================+
|``'surrogatepass'``| utf-8 | Allow encoding and decoding of surrogate |
| | | codes in UTF-8. |
+-------------------+---------+-------------------------------------------+
.. versionadded:: 3.1
The ``'surrogateescape'`` and ``'surrogatepass'`` error handlers.
2007-08-15 11:28:22 -03:00
The set of allowed values can be extended via :meth:`register_error`.
.. _codec-objects:
Codec Objects
^^^^^^^^^^^^^
The :class:`Codec` class defines these methods which also define the function
interfaces of the stateless encoder and decoder:
.. method:: Codec.encode(input[, errors])
Encodes the object *input* and returns a tuple (output object, length consumed).
Encoding converts a string object to a bytes object using a particular
2007-08-15 11:28:22 -03:00
character set encoding (e.g., ``cp1252`` or ``iso-8859-1``).
*errors* defines the error handling to apply. It defaults to ``'strict'``
handling.
The method may not store state in the :class:`Codec` instance. Use
:class:`StreamCodec` for codecs which have to keep state in order to make
encoding/decoding efficient.
The encoder must be able to handle zero length input and return an empty object
of the output object type in this situation.
.. method:: Codec.decode(input[, errors])
Decodes the object *input* and returns a tuple (output object, length
consumed). Decoding converts a bytes object encoded using a particular
character set encoding to a string object.
2007-08-15 11:28:22 -03:00
*input* must be a bytes object or one which provides the read-only character
buffer interface -- for example, buffer objects and memory mapped files.
2007-08-15 11:28:22 -03:00
*errors* defines the error handling to apply. It defaults to ``'strict'``
handling.
The method may not store state in the :class:`Codec` instance. Use
:class:`StreamCodec` for codecs which have to keep state in order to make
encoding/decoding efficient.
The decoder must be able to handle zero length input and return an empty object
of the output object type in this situation.
The :class:`IncrementalEncoder` and :class:`IncrementalDecoder` classes provide
the basic interface for incremental encoding and decoding. Encoding/decoding the
input isn't done with one call to the stateless encoder/decoder function, but
with multiple calls to the :meth:`encode`/:meth:`decode` method of the
incremental encoder/decoder. The incremental encoder/decoder keeps track of the
encoding/decoding process during method calls.
The joined output of calls to the :meth:`encode`/:meth:`decode` method is the
same as if all the single inputs were joined into one, and this input was
encoded/decoded with the stateless encoder/decoder.
.. _incremental-encoder-objects:
IncrementalEncoder Objects
^^^^^^^^^^^^^^^^^^^^^^^^^^
The :class:`IncrementalEncoder` class is used for encoding an input in multiple
steps. It defines the following methods which every incremental encoder must
define in order to be compatible with the Python codec registry.
.. class:: IncrementalEncoder([errors])
Constructor for an :class:`IncrementalEncoder` instance.
All incremental encoders must provide this constructor interface. They are free
to add additional keyword arguments, but only the ones defined here are used by
the Python codec registry.
The :class:`IncrementalEncoder` may implement different error handling schemes
by providing the *errors* keyword argument. These parameters are predefined:
* ``'strict'`` Raise :exc:`ValueError` (or a subclass); this is the default.
* ``'ignore'`` Ignore the character and continue with the next.
* ``'replace'`` Replace with a suitable replacement character
* ``'xmlcharrefreplace'`` Replace with the appropriate XML character reference
* ``'backslashreplace'`` Replace with backslashed escape sequences.
The *errors* argument will be assigned to an attribute of the same name.
Assigning to this attribute makes it possible to switch between different error
handling strategies during the lifetime of the :class:`IncrementalEncoder`
object.
The set of allowed values for the *errors* argument can be extended with
:func:`register_error`.
.. method:: encode(object[, final])
2007-08-15 11:28:22 -03:00
Encodes *object* (taking the current state of the encoder into account)
and returns the resulting encoded object. If this is the last call to
:meth:`encode` *final* must be true (the default is false).
2007-08-15 11:28:22 -03:00
.. method:: reset()
2007-08-15 11:28:22 -03:00
Reset the encoder to the initial state. The output is discarded: call
``.encode('', final=True)`` to reset the encoder and to get the output.
2007-08-15 11:28:22 -03:00
.. method:: IncrementalEncoder.getstate()
Return the current state of the encoder which must be an integer. The
implementation should make sure that ``0`` is the most common state. (States
that are more complicated than integers can be converted into an integer by
marshaling/pickling the state and encoding the bytes of the resulting string
into an integer).
.. method:: IncrementalEncoder.setstate(state)
Set the state of the encoder to *state*. *state* must be an encoder state
returned by :meth:`getstate`.
.. _incremental-decoder-objects:
IncrementalDecoder Objects
^^^^^^^^^^^^^^^^^^^^^^^^^^
The :class:`IncrementalDecoder` class is used for decoding an input in multiple
steps. It defines the following methods which every incremental decoder must
define in order to be compatible with the Python codec registry.
.. class:: IncrementalDecoder([errors])
Constructor for an :class:`IncrementalDecoder` instance.
All incremental decoders must provide this constructor interface. They are free
to add additional keyword arguments, but only the ones defined here are used by
the Python codec registry.
The :class:`IncrementalDecoder` may implement different error handling schemes
by providing the *errors* keyword argument. These parameters are predefined:
* ``'strict'`` Raise :exc:`ValueError` (or a subclass); this is the default.
* ``'ignore'`` Ignore the character and continue with the next.
* ``'replace'`` Replace with a suitable replacement character.

2007-08-15 11:28:22 -03:00
object.
The set of allowed values for the *errors* argument can be extended with
:func:`register_error`.
.. method:: decode(object[, final])
2007-08-15 11:28:22 -03:00
Decodes *object* (taking the current state of the decoder into account)
and returns the resulting decoded object. If this is the last call to
:meth:`decode` *final* must be true (the default is false). If *final* is
true the decoder must decode the input completely and must flush all
buffers. If this isn't possible (e.g. because of incomplete byte sequences
at the end of the input) it must initiate error handling just like in the
stateless case (which might raise an exception).
2007-08-15 11:28:22 -03:00
.. method:: reset()
2007-08-15 11:28:22 -03:00
Reset the decoder to the initial state.
2007-08-15 11:28:22 -03:00
.. method:: getstate()
2007-08-15 11:28:22 -03:00
Return the current state of the decoder. This must be a tuple with two
items, the first must be the buffer containing the still undecoded
input. The second must be an integer and can be additional state
info. (The implementation should make sure that ``0`` is the most common
additional state info.) If this additional state info is ``0`` it must be
possible to set the decoder to the state which has no input buffered and
``0`` as the additional state info, so that feeding the previously
buffered input to the decoder returns it to the previous state without
producing any output. (Additional state info that is more complicated than
integers can be converted into an integer by marshaling/pickling the info
and encoding the bytes of the resulting string into an integer.)
2007-08-15 11:28:22 -03:00
.. method:: setstate(state)
Set the state of the encoder to *state*. *state* must be a decoder state
returned by :meth:`getstate`.
2007-08-15 11:28:22 -03:00
The :class:`StreamWriter` and :class:`StreamReader` classes provide generic
working interfaces which can be used to implement new encoding submodules very
easily. See :mod:`encodings.utf_8` for an example of how this is done.
.. _stream-writer-objects:
StreamWriter Objects
^^^^^^^^^^^^^^^^^^^^
The :class:`StreamWriter` class is a subclass of :class:`Codec` and defines the
following methods which every stream writer must define in order to be
compatible with the Python codec registry.
.. class:: StreamWriter(stream[, errors])
Constructor for a :class:`StreamWriter` instance.
All stream writers must provide this constructor interface. They are free to add
additional keyword arguments, but only the ones defined here are used by the
Python codec registry.
*stream* must be a file-like object open for writing binary data.
The :class:`StreamWriter` may implement different error handling schemes by
providing the *errors* keyword argument. These parameters are predefined:
* ``'strict'`` Raise :exc:`ValueError` (or a subclass); this is the default.
* ``'ignore'`` Ignore the character and continue with the next.
* ``'replace'`` Replace with a suitable replacement character
* ``'xmlcharrefreplace'`` Replace with the appropriate XML character reference
* ``'backslashreplace'`` Replace with backslashed escape sequences.
The *errors* argument will be assigned to an attribute of the same name.
Assigning to this attribute makes it possible to switch between different error
handling strategies during the lifetime of the :class:`StreamWriter` object.
The set of allowed values for the *errors* argument can be extended with
:func:`register_error`.
.. method:: write(object)
Writes the object's contents encoded to the stream.
2007-08-15 11:28:22 -03:00
.. method:: writelines(list)
2007-08-15 11:28:22 -03:00
Writes the concatenated list of strings to the stream (possibly by reusing
the :meth:`write` method).
2007-08-15 11:28:22 -03:00
.. method:: reset()
2007-08-15 11:28:22 -03:00
Flushes and resets the codec buffers used for keeping state.
2007-08-15 11:28:22 -03:00
Calling this method should ensure that the data on the output is put into
a clean state that allows appending of new fresh data without having to
rescan the whole stream to recover state.
2007-08-15 11:28:22 -03:00
In addition to the above methods, the :class:`StreamWriter` must also inherit
all other methods and attributes from the underlying stream.
.. _stream-reader-objects:
StreamReader Objects
^^^^^^^^^^^^^^^^^^^^
The :class:`StreamReader` class is a subclass of :class:`Codec` and defines the
following methods which every stream reader must define in order to be
compatible with the Python codec registry.
.. class:: StreamReader(stream[, errors])
Constructor for a :class:`StreamReader` instance.
All stream readers must provide this constructor interface. They are free to add
additional keyword arguments, but only the ones defined here are used by the
Python codec registry.
*stream* must be a file-like object open for reading (binary) data.
The :class:`StreamReader` may implement different error handling schemes by
providing the *errors* keyword argument. These parameters are defined:
* ``'strict'`` Raise :exc:`ValueError` (or a subclass); this is the default.
* ``'ignore'`` Ignore the character and continue with the next.
* ``'replace'`` Replace with a suitable replacement character.
The *errors* argument will be assigned to an attribute of the same name.
Assigning to this attribute makes it possible to switch between different error
handling strategies during the lifetime of the :class:`StreamReader` object.
The set of allowed values for the *errors* argument can be extended with
:func:`register_error`.
.. method:: read([size[, chars, [firstline]]])
2007-08-15 11:28:22 -03:00
Decodes data from the stream and returns the resulting object.
2007-08-15 11:28:22 -03:00
*chars* indicates the number of characters to read from the
stream. :func:`read` will never return more than *chars* characters, but
it might return less, if there are not enough characters available.
2007-08-15 11:28:22 -03:00
*size* indicates the approximate maximum number of bytes to read from the
stream for decoding purposes. The decoder can modify this setting as
appropriate. The default value -1 indicates to read and decode as much as
possible. *size* is intended to prevent having to decode huge files in
one step.
2007-08-15 11:28:22 -03:00
*firstline* indicates that it would be sufficient to only return the first
line, if there are decoding errors on later lines.
2007-08-15 11:28:22 -03:00
The method should use a greedy read strategy meaning that it should read
as much data as is allowed within the definition of the encoding and the
given size, e.g. if optional encoding endings or state markers are
available on the stream, these should be read too.
2007-08-15 11:28:22 -03:00
.. method:: readline([size[, keepends]])
2007-08-15 11:28:22 -03:00
Read one line from the input stream and return the decoded data.
2007-08-15 11:28:22 -03:00
*size*, if given, is passed as size argument to the stream's
:meth:`readline` method.
2007-08-15 11:28:22 -03:00
If *keepends* is false line-endings will be stripped from the lines
returned.
2007-08-15 11:28:22 -03:00
.. method:: readlines([sizehint[, keepends]])
2007-08-15 11:28:22 -03:00
Read all lines available on the input stream and return them as a list of
lines.
2007-08-15 11:28:22 -03:00
Line-endings are implemented using the codec's decoder method and are
included in the list entries if *keepends* is true.
2007-08-15 11:28:22 -03:00
*sizehint*, if given, is passed as the *size* argument to the stream's
:meth:`read` method.
2007-08-15 11:28:22 -03:00
.. method:: reset()
2007-08-15 11:28:22 -03:00
Resets the codec buffers used for keeping state.
Note that no stream repositioning should take place. This method is
primarily intended to be able to recover from decoding errors.
2007-08-15 11:28:22 -03:00
In addition to the above methods, the :class:`StreamReader` must also inherit
all other methods and attributes from the underlying stream.
The next two base classes are included for convenience. They are not needed by
the codec registry, but may provide useful in practice.
.. _stream-reader-writer:
StreamReaderWriter Objects
^^^^^^^^^^^^^^^^^^^^^^^^^^
The :class:`StreamReaderWriter` allows wrapping streams which work in both read
and write modes.
The design is such that one can use the factory functions returned by the
:func:`lookup` function to construct the instance.
.. class:: StreamReaderWriter(stream, Reader, Writer, errors)
Creates a :class:`StreamReaderWriter` instance. *stream* must be a file-like
object. *Reader* and *Writer* must be factory functions or classes providing the
:class:`StreamReader` and :class:`StreamWriter` interface resp. Error handling
is done in the same way as defined for the stream readers and writers.
:class:`StreamReaderWriter` instances define the combined interfaces of
:class:`StreamReader` and :class:`StreamWriter` classes. They inherit all other
methods and attributes from the underlying stream.
.. _stream-recoder-objects:
StreamRecoder Objects
^^^^^^^^^^^^^^^^^^^^^
The :class:`StreamRecoder` provide a frontend - backend view of encoding data
which is sometimes useful when dealing with different encoding environments.
The design is such that one can use the factory functions returned by the
:func:`lookup` function to construct the instance.
.. class:: StreamRecoder(stream, encode, decode, Reader, Writer, errors)
Creates a :class:`StreamRecoder` instance which implements a two-way conversion:
*encode* and *decode* work on the frontend (the input to :meth:`read` and output
of :meth:`write`) while *Reader* and *Writer* work on the backend (reading and
writing to the stream).
You can use these objects to do transparent direct recodings from e.g. Latin-1
to UTF-8 and back.
*stream* must be a file-like object.
*encode*, *decode* must adhere to the :class:`Codec` interface. *Reader*,
*Writer* must be factory functions or classes providing objects of the
:class:`StreamReader` and :class:`StreamWriter` interface respectively.
*encode* and *decode* are needed for the frontend translation, *Reader* and
*Writer* for the backend translation.
2007-08-15 11:28:22 -03:00
Error handling is done in the same way as defined for the stream readers and
writers.
2007-08-15 11:28:22 -03:00
:class:`StreamRecoder` instances define the combined interfaces of
:class:`StreamReader` and :class:`StreamWriter` classes. They inherit all other
methods and attributes from the underlying stream.
.. _encodings-overview:
Encodings and Unicode
---------------------
Strings are stored internally as sequences of codepoints in range ``0 - 10FFFF``
(see :pep:`393` for more details about the implementation).
Once a string object is used outside of CPU and memory, CPU endianness
2007-08-15 11:28:22 -03:00
and how these arrays are stored as bytes become an issue. Transforming a
string object into a sequence of bytes is called encoding and recreating the
string object from the sequence of bytes is known as decoding. There are many
2007-08-15 11:28:22 -03:00
different methods for how this transformation can be done (these methods are
also called encodings). The simplest method is to map the codepoints 0-255 to
the bytes ``0x0``-``0xff``. This means that a string object that contains
2007-08-15 11:28:22 -03:00
codepoints above ``U+00FF`` can't be encoded with this method (which is called
``'latin-1'`` or ``'iso-8859-1'``). :func:`str.encode` will raise a
2007-08-15 11:28:22 -03:00
:exc:`UnicodeEncodeError` that looks like this: ``UnicodeEncodeError: 'latin-1'
codec can't encode character '\u1234' in position 3: ordinal not in
2007-08-15 11:28:22 -03:00
range(256)``.
There's another group of encodings (the so called charmap encodings) that choose
a different subset of all Unicode code points and how these codepoints are
2007-08-15 11:28:22 -03:00
mapped to the bytes ``0x0``-``0xff``. To see how this is done simply open
e.g. :file:`encodings/cp1252.py` (which is an encoding that is used primarily on
Windows). There's a string constant with 256 characters that shows you which
character is mapped to which byte value.
2011-10-25 04:40:38 -03:00
All of these encodings can only encode 256 of the 1114112 codepoints
defined in Unicode. A simple and straightforward way that can store each Unicode
2011-10-25 04:40:38 -03:00
code point, is to store each codepoint as four consecutive bytes. There are two
possibilities: store the bytes in big endian or in little endian order. These
two encodings are called ``UTF-32-BE`` and ``UTF-32-LE`` respectively. Their
disadvantage is that if e.g. you use ``UTF-32-BE`` on a little endian machine you
will always have to swap bytes on encoding and decoding. ``UTF-32`` avoids this
problem: bytes will always be in natural endianness. When these bytes are read
2007-08-15 11:28:22 -03:00
by a CPU with a different endianness, then bytes have to be swapped though. To
2011-10-25 04:40:38 -03:00
be able to detect the endianness of a ``UTF-16`` or ``UTF-32`` byte sequence,
there's the so called BOM ("Byte Order Mark"). This is the Unicode character
``U+FEFF``. This character can be prepended to every ``UTF-16`` or ``UTF-32``
byte sequence. The byte swapped version of this character (``0xFFFE``) is an
illegal character that may not appear in a Unicode text. So when the
first character in an ``UTF-16`` or ``UTF-32`` byte sequence
2007-08-15 11:28:22 -03:00
appears to be a ``U+FFFE`` the bytes have to be swapped on decoding.
2011-10-25 04:40:38 -03:00
Unfortunately the character ``U+FEFF`` had a second purpose as
a ``ZERO WIDTH NO-BREAK SPACE``: a character that has no width and doesn't allow
2007-08-15 11:28:22 -03:00
a word to be split. It can e.g. be used to give hints to a ligature algorithm.
With Unicode 4.0 using ``U+FEFF`` as a ``ZERO WIDTH NO-BREAK SPACE`` has been
deprecated (with ``U+2060`` (``WORD JOINER``) assuming this role). Nevertheless
2011-10-25 04:40:38 -03:00
Unicode software still must be able to handle ``U+FEFF`` in both roles: as a BOM
2007-08-15 11:28:22 -03:00
it's a device to determine the storage layout of the encoded bytes, and vanishes
once the byte sequence has been decoded into a string; as a ``ZERO WIDTH
2007-08-15 11:28:22 -03:00
NO-BREAK SPACE`` it's a normal character that will be decoded like any other.
There's another encoding that is able to encoding the full range of Unicode
characters: UTF-8. UTF-8 is an 8-bit encoding, which means there are no issues
with byte order in UTF-8. Each byte in a UTF-8 byte sequence consists of two
2011-10-25 04:40:38 -03:00
parts: marker bits (the most significant bits) and payload bits. The marker bits
are a sequence of zero to four ``1`` bits followed by a ``0`` bit. Unicode characters are
2007-08-15 11:28:22 -03:00
encoded like this (with x being payload bits, which when concatenated give the
Unicode character):
+-----------------------------------+----------------------------------------------+
| Range | Encoding |
+===================================+==============================================+
| ``U-00000000`` ... ``U-0000007F`` | 0xxxxxxx |
+-----------------------------------+----------------------------------------------+
| ``U-00000080`` ... ``U-000007FF`` | 110xxxxx 10xxxxxx |
+-----------------------------------+----------------------------------------------+
| ``U-00000800`` ... ``U-0000FFFF`` | 1110xxxx 10xxxxxx 10xxxxxx |
+-----------------------------------+----------------------------------------------+
| ``U-00010000`` ... ``U-0010FFFF`` | 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx |
2007-08-15 11:28:22 -03:00
+-----------------------------------+----------------------------------------------+
The least significant bit of the Unicode character is the rightmost x bit.
As UTF-8 is an 8-bit encoding no BOM is required and any ``U+FEFF`` character in
the decoded string (even if it's the first character) is treated as a ``ZERO
WIDTH NO-BREAK SPACE``.
2007-08-15 11:28:22 -03:00
Without external information it's impossible to reliably determine which
encoding was used for encoding a string. Each charmap encoding can
2007-08-15 11:28:22 -03:00
decode any random byte sequence. However that's not possible with UTF-8, as
UTF-8 byte sequences have a structure that doesn't allow arbitrary byte

sequences. To increase the reliability with which a UTF-8 encoding can be
2007-08-15 11:28:22 -03:00
detected, Microsoft invented a variant of UTF-8 (that Python 2.5 calls
``"utf-8-sig"``) for its Notepad program: Before any of the Unicode characters
is written to the file, a UTF-8 encoded BOM (which looks like this as a byte
sequence: ``0xef``, ``0xbb``, ``0xbf``) is written. As it's rather improbable
that any charmap encoded file starts with these byte values (which would e.g.
map to
| LATIN SMALL LETTER I WITH DIAERESIS
| RIGHT-POINTING DOUBLE ANGLE QUOTATION MARK
| INVERTED QUESTION MARK
2011-10-25 04:40:38 -03:00
in iso-8859-1), this increases the probability that a ``utf-8-sig`` encoding can be
2007-08-15 11:28:22 -03:00
correctly guessed from the byte sequence. So here the BOM is not used to be able
to determine the byte order used for generating the byte sequence, but as a
signature that helps in guessing the encoding. On encoding the utf-8-sig codec
will write ``0xef``, ``0xbb``, ``0xbf`` as the first three bytes to the file. On
2011-10-25 04:40:38 -03:00
decoding ``utf-8-sig`` will skip those three bytes if they appear as the first
three bytes in the file. In UTF-8, the use of the BOM is discouraged and
should generally be avoided.

Standard Encodings
------------------
Python comes with a number of codecs built-in, either implemented as C functions
or with dictionaries as mapping tables. The following table lists the codecs by
name, together with a few common aliases, and the languages for which the
encoding is likely used. Neither the list of aliases nor the list of languages
is meant to be exhaustive. Notice that spelling alternatives that only differ in

case or use a hyphen instead of an underscore are also valid aliases; therefore,
e.g. ``'utf-8'`` is a valid alias for the ``'utf_8'`` codec.

Some common encodings can bypass the codecs lookup machinery to
improve performance. These optimization opportunities are only
recognized by CPython for a limited set of aliases: utf-8, utf8,
latin-1, latin1, iso-8859-1, mbcs (Windows only), ascii, utf-16,
and utf-32. Using alternative spellings for these encodings may
result in slower execution.

Many of the character sets support the same languages. They vary in individual
characters (e.g. whether the EURO SIGN is supported or not), and in the
assignment of characters to code positions. For the European languages in
particular, the following variants typically exist:
* an ISO 8859 codeset
* a Microsoft Windows code page, which is typically derived from a 8859 codeset,
but replaces control characters with additional graphic characters
* an IBM EBCDIC code page
* an IBM PC code page, which is ASCII compatible

:mod:`encodings.idna` --- Internationalized Domain Names in Applications
------------------------------------------------------------------------
.. module:: encodings.idna
:synopsis: Internationalized Domain Names implementation
.. moduleauthor:: Martin v. Löwis
This module implements :rfc:`3490` (Internationalized Domain Names in
Applications) and :rfc:`3492` (Nameprep: A Stringprep Profile for
Internationalized Domain Names (IDN)). It builds upon the ``punycode`` encoding
and :mod:`stringprep`.
These RFCs together define a protocol to support non-ASCII characters in domain
names. A domain name containing non-ASCII characters (such as
``www.Alliancefrançaise.nu``) is converted into an ASCII-compatible encoding
(ACE, such as ``www.xn--alliancefranaise-npb.nu``). The ACE form of the domain
name is then used in all places where arbitrary characters are not allowed by
the protocol, such as DNS queries, HTTP :mailheader:`Host` fields, and so
on. This conversion is carried out in the application; if possible invisible to
the user: The application should transparently convert Unicode domain labels to
IDNA on the wire, and convert back ACE labels to Unicode before presenting them
to the user.
Python supports this conversion in several ways: the ``idna`` codec performs
conversion between Unicode and ACE, separating an input string into labels
based on the separator characters defined in `section 3.1`_ (1) of :rfc:`3490`
and converting each label to ACE as required, and conversely separating an input
byte string into labels based on the ``.`` separator and converting any ACE
labels found into unicode. Furthermore, the :mod:`socket` module
2007-08-15 11:28:22 -03:00
transparently converts Unicode host names to ACE, so that applications need not
be concerned about converting host names themselves when they pass them to the
socket module. On top of that, modules that have host names as function
2008-05-26 13:32:26 -03:00
parameters, such as :mod:`http.client` and :mod:`ftplib`, accept Unicode host
names (:mod:`http.client` then also transparently sends an IDNA hostname in the
2007-08-15 11:28:22 -03:00
:mailheader:`Host` field if it sends that field at all).
.. _section 3.1: http://tools.ietf.org/html/rfc3490#section-3.1
2007-08-15 11:28:22 -03:00
When receiving host names from the wire (such as in reverse name lookup), no
automatic conversion to Unicode is performed: Applications wishing to present
such host names to the user should decode them to Unicode.
The module :mod:`encodings.idna` also implements the nameprep procedure, which
performs certain normalizations on host names, to achieve case-insensitivity of
international domain names, and to unify similar characters. The nameprep
functions can be used directly if desired.
.. function:: nameprep(label)
Return the nameprepped version of *label*. The implementation currently assumes
query strings, so ``AllowUnassigned`` is true.
.. function:: ToASCII(label)
Convert a label to ASCII, as specified in :rfc:`3490`. ``UseSTD3ASCIIRules`` is
assumed to be false.
.. function:: ToUnicode(label)
Convert a label to Unicode, as specified in :rfc:`3490`.
:mod:`encodings.mbcs` --- Windows ANSI codepage
-----------------------------------------------
.. module:: encodings.mbcs
:synopsis: Windows ANSI codepage
Encode operand according to the ANSI codepage (CP_ACP).
Availability: Windows only.
.. versionchanged:: 3.3
Support any error handler.
.. versionchanged:: 3.2
Before 3.2, the *errors* argument was ignored; ``'replace'`` was always used
to encode, and ``'ignore'`` to decode.

:mod:`encodings.utf_8_sig` --- UTF-8 codec with BOM signature
-------------------------------------------------------------
.. module:: encodings.utf_8_sig
:synopsis: UTF-8 codec with BOM signature
.. moduleauthor:: Walter Dörwald
This module implements a variant of the UTF-8 codec: On encoding a UTF-8 encoded
BOM will be prepended to the UTF-8 encoded bytes. For the stateful encoder this
is only done once (on the first write to the byte stream). For decoding an
optional UTF-8 encoded BOM at the start of the data will be skipped.
