If we already have those, why aren't they documented? If they exist, they
should be the first thing in the codecs module docs and the porting guide
should list them as the replacement for the method versions when using
encodings that aren't directly related to the text model, or when the input
buffer for decoding isn't a bytes or bytearray object.
