Here's an idea I don't think I've seen before:

bytes.recode(b, src_encoding, dest_encoding)

This requires the user to state up-front what the source encoding is.
One of the big problems that I see with the whole encoding mess is that
so much of it contains implicit assumptions about the source encoding;
this gets away from that.
