I guess this means that you have non-ascii characters in your source 
code but you have not included an encoding declaration. From "What's New 
in Python 2.5":

ASCII is now the default encoding for modules. It's now a syntax error 
if a module contains string literals with 8-bit characters but doesn't 
have an encoding declaration. In Python 2.4 this triggered a warning, 
not a syntax error. See PEP 263 for how to declare a module's encoding; 
for example, you might add a line like this near the top of the source file:
# -*- coding: latin1 -*-
