To me this still sounds like the best approach. Converting 'lists and 
stuff' should not be too hard. This method from CMFDefault.utils might 
be useful for that:

def toUnicode(value, charset=None):
     """ Convert value to unicode.
     """
     if isinstance(value, str):
         return charset and unicode(value, charset) or unicode(value)
     elif isinstance(value, list):
         return [ toUnicode(val, charset) for val in value ]
     elif isinstance(value, tuple):
         return tuple( [ toUnicode(val, charset) for val in value ] )
     elif isinstance(value, dict):
         for key, val in value.items():
             value[key] = toUnicode(val, charset)
         return value
     else:
         return value
