The source of the problem is probably the fact
that Python 2.x defaults to the ASCII encoding for text strings.
Therefore, when you interact with Unicode text,
you get all sort of encoding problems.

You can configure your installation of Python to go for utf-8
/usr/lib/python2.5/site.py:

def setencoding():
    """Set the string encoding used by the Unicode implementation.  The
    default is 'ascii', but if you're willing to experiment, you can
    change this."""
    encoding = "utf-8" # Default value set by _PyUnicode_Init()

This should solve the Unicode problems in a painless way.
