@ -130,15 +130,22 @@ Here are the methods of the :class:`Message` class:
string naming a character set, or ``None``. If it is a string, it will
be converted to a :class:`~email.charset.Charset` instance. If *charset*
is ``None``, the ``charset`` parameter will be removed from the
:mailheader:`Content-Type` header. Anything else will generate a
:exc:`TypeError`.
:mailheader:`Content-Type` header (the message will not be otherwise
modified). Anything else will generate a :exc:`TypeError`.
The message will be assumed to be of type :mimetype:`text/\*` encoded with
*charset.input_charset*. It will be converted to *charset.output_charset*
and encoded properly, if needed, when generating the plain text
representation of the message. MIME headers (:mailheader:`MIME-Version`,
:mailheader:`Content-Type`, :mailheader:`Content-Transfer-Encoding`) will
be added as needed.
If there is no existing :mailheader:`MIME-Version` header one will be
added. If there is no existing :mailheader:`Content-Type` header, one
will be added with a value of :mimetype:`text/plain`. Whether the
:mailheader:`Content-Type` header already exists or not, its ``charset``
parameter will be set to *charset.output_charset*. If
*charset.input_charset* and *charset.output_charset* differ, the payload
will be re-encoded to the *output_charset*. If there is no existing
:mailheader:`Content-Transfer-Encoding` header, then the payload will be
transfer-encoded, if needed, using the specified
:class:`~email.charset.Charset`, and a header with the appropriate value
will be added. If a :mailheader:`Content-Transfer-Encoding` header
already exists, the payload is assumed to already be correctly encoded
using that :mailheader:`Content-Transfer-Encoding` and is not modified.
