Unicode support...

This is probably a FAQ, and in November Robin Dunn said
that he was looking into it... so I was wondering.
Thank you!

P.S. In the intrem, do you know how to cast a unicode
      string into a ascii string? Hmm. Not obvious.

Starting with 2.2.5 the wrappers call PyString_AsStringAndSize to convert
parameters into wxString objects. That function will automatically convert
unicode objects to strings using the default encoding. Beyond that I'm open
to suggestions.

I wrote a small module to deal with the problem that works
for Py 1.5 and Py 2.0. Also enables you to use Gordon's
installer to make .exe's that use encode.

import python_compatibility

wxWhatever( python_compatibility( strarg ) )

# Provide compatibility between python 1.5.2 and Python 2.0

def _p15_encode( s ):
  return s

def _p20_encode( s ):
  return s.encode( 'UTF-8' )

import sys, string
version = string.split( sys.version, ' ' )

is_p20 = version[0] >= '2.0'

if is_p20:
  import encodings.utf_8 # needed when turning .py into .exe

encode = is_p20 and _p20_encode or _p15_encode

And what if the string has letters of different code pages in it -
  some greek or cyrillics letters or german umlauts ?
