Hi,
I'm new to matplotlib which is really good job 
and I'm currently
fighting against character encodings :-(.
Being working under win2k/western Europe, I finally found on the web
that using a cp850 source encoding definition was working with 'print'
only if you also encode your strings from cp1252! (for us/en users:
windows uses cp1252 but the console uses cp850, this message was written
using iso-8859-1).
Example:
# -*- coding: cp850 -*-
print unicode('texte fran�ais','cp1252')
texte fran�ais
If I do the same with the matplotlib 0.54 'title' function I get an error telling the 'ascii' codec cannot encode my '�':
# -*- coding: cp850 -*-
from matplotlib.matlab import *
plot([1,2,3,4])
title(unicode('texte fran�ais','cp1252'))
Exception in tkinter callback
Traceback ...
[...]
font.set_text(s, 0.0) # ...
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe7' in
position 10: ordinal not in range(128)
···
-----------------
With matplotlib 0.61 I get this error:
>>> title(unicode('texte fran�ais','cp1252'))
Traceback (most recent call last):

---------------
I tried to add different encodings (ie. unicode('texte fran�ais',
'cp1252').encode(...) with utf-8, cp1252, cp850...) without success.
Naturally if I omit any unicode translation, it does not crash but the
string is not correctly rendered. Does it mean that matplotlib currently
expects 'ascii' strings only to passed to its text functions?
