I might want to have a deeper look at the str/unicode business in Python:
http://farmdev.com/talks/unicode/

What is the type of 'value' variable? Isn't it a QString by chance? If it
is, then you would be probably better off by using QRegExp for the search.
Or instead of doing str(value) that doesn't handle unicode characters
correctly you should use unicode(value). Or if it is a utf-8 encoded string
(or using other encoding) then decode it to a unicode string.
