Description:
------------
wddx gets confused if you try to serialize a string with utf8 characters (like the one below, it contains 'z with dot above', 'o acute', 'l stroke' and 'w' - in case it gets messed up somehow).

serialized string will contain <char code='C5'/><char code='BC'/> ... etc, which will get fed into xml_utf8_decode byte by byte (after decoding the hex value), totally wrecking the output.

Hackish patch which fixes this (whitespace mangled mercilessly, adjust to taste):
