[issue17828] More informative error handling when encoding and decoding

[Nick Coghlan]

Nick Coghlan added the comment:

Ezio pointed out on IRC that the extra type checks in str.encode, bytes.decode and bytearray.decode should reference the appopriate codecs module function in addition to the codec in use.

So if str.encode produces something other than bytes, it should reference codecs.encode, while the binary decoding methods should mention codecs.decode if they produce something other than str.
