[Python-3000] PEP 3138- String representation in Python 3000

["Martin v. Löwis"]

> The Unicode consortium usually uses the terms "UCS2" and "UCS4"
> when referring to Unicode as "character set", but even there
> you have an ordering which makes it an encoding.

The Unicode consortium uses the term "coded character set" to describe
the assignment of characters in the set to numbers, and "character
encoding scheme" to refer to an algorithm that produces a sequence of
bytes, and doesn't use the term "encoding" altogether, see
