Bug description:  WDDX bad character encoding

Description:
------------
WDDX serializes control charactes using a <char code="XX"/> construct,
However, the code contains sign extension bug, and on platforms with
signed char the result XX contains incorrect (sign-extended) code.

This affects e.g. UTF8-encoded non-ASCII text, which can contain
characters in 128-160 range.

Fix:

Reproduce code:
---------------
On UNIX with iso-8859-1 locale:

echo wddx_serialize_value(chr(1))."\n";
echo wddx_serialize_value(chr(128))."\n";


Expected result:
----------------
<wddxPacket version='1.0'><header/><data><string><char
code='01'/></string></data></wddxPacket>
<wddxPacket version='1.0'><header/><data><string><char
code='80'/></string></data></wddxPacket>



Actual result:
--------------
<wddxPacket version='1.0'><header/><data><string><char
code='01'/></string></data></wddxPacket>
<wddxPacket version='1.0'><header/><data><string><char
code='FFFFFF80'/></string></data></wddxPacket>
