[RFC] Merge charsets and encodings

I fully agree with that proposal.

Don't forget the 'binary' encoding. It does nothing, but is a
convenient way to distinguish text strings from binary streams of
chars

We should also consider a cleanup of the encoding names, preferably
using the forms standarized by Unicode.
