r81854 removes codecs.charbuffer_encode() (and t# parsing format) from Python 3.2 (blocked in 3.1: r81855).

--

My problem with codecs.readbuffer_encode() is that it does accept byte *and* character strings. If you want to get a byte string, just use bytes(input). If you want to convert a character string to a byte string, use input.encode("utf-8"). But accepting both types may lead to mojibake as we had in Python2.

This is related to #7475: we have to decide if we drop completly this  (currently unused) feature (eg. remove codecs.readbuffer_encode()), or if we "reenable" this feature again (reintroduce hex, bz2, rot13, ... codecs). This discussion should occur on the mailing list.
