I was rejecting completly transform codecs, but I changed my mind. I'm trying to accept that codecs.encode/decode functions were present from the beginning and that they should be functions :-)

My request to remove extra code on the exceptions handling was specific to pure Unicode encodings (like UTF-8. The code can be kept for codecs.encode/decode.

The impact of my request should only impact misused third party transform codecs. You would just get as much info that you are getting with Python 3.3.
