OK, this error is in your code, not the ConfigParser. The problem is with
",".join(self.recent_files)

Are the entries in self.recent_files unicode strings? If so, then I
think the join is trying to convert to a string using the default
codec. Try

self.cfg.set('File Settings','Recent files',
','.join(name.encode('utf-8') for name in self.recent_files))

Looking at the ConfigParser.write() code, it wants the values to be
strings or convertible to strings by calling str(), so non-ascii
unicode values will be a problem there. I would use plain strings for
all the interaction with ConfigParser and convert to Unicode yourself.
