These two methods provide direct access + to the corresponding decoders and encoders of the registered codecs. + + To enhance the usability of the .encode() method, the special + casing of Unicode object return values was dropped (Unicode objects + were auto-magically converted to string using the default encoding). + + Both methods will now return whatever the codec in charge of the + requested encoding returns as object, e.g. Unicode codecs will + return Unicode objects when decoding is requested ("äöü".decode("latin-1") + will return u"äöü"). This enables codec writer to create codecs + for various simple to use conversions. + + New codecs were added to demonstrate these new features (the .encode() + and .decode() columns indicate the type of the returned objects): + + Name | .encode() | .decode() | Description + ---------------------------------------------------------------------- + uu | string | string | UU codec (e.g. for email) + base64 | string | string | base64 codec + zlib | string | string | zlib compression + hex | string | string | 2-byte hex codec + rot-13 | string | Unicode | ROT-13 Unicode charmap codec + - Some operating systems now support the concept of a default Unicode encoding for file system operations.
