Bug description: wddx mangles utf8 characters in serialized strings
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):
