Issue #19619 : Blacklist non-text codecs in method API
...
str.encode, bytes.decode and bytearray.decode now use an
internal API to throw LookupError for known non-text encodings,
rather than attempting the encoding or decoding operation and
then throwing a TypeError for an unexpected output type.
The latter mechanism remains in place for third party non-text
encodings.

Issue #12892 : The utf-16* and utf-32* codecs now reject (lone) surrogates.
...
The utf-16* and utf-32* encoders no longer allow surrogate code points
(U+D800-U+DFFF) to be encoded.
The utf-32* decoders no longer decode byte sequences that correspond to
surrogate code points.
The surrogatepass error handler now works with the utf-16* and utf-32* codecs.
Based on patches by Victor Stinner and Kang-Hao (Kenny) Lu.
