For what's new in Python 2.3, see http://www.python.org/doc/2.3/whatsnew/

For the above issue, look at item 3 in the list:
3 PEP 263: Source Code Encodings

And then go on to the PEP itself:
http://www.python.org/peps/pep-0263.html

Basically, you can declare the encoding of a source file so that the
non-ASCII characters are understood as intended.  Sample

> #!/usr/bin/env python
> # -*- coding: UTF-8 -*-

The declaration must be very early in the source file (see the PEP).
Identifiers are still restricted to a subset of ASCII characters.
(No ASCII character has a 1 in the high order bit.)
