[phpxmlrpc] Special special chars in XML Response

The answer was clearly given without enough thinking...

The first question is: are you using the lib to write the client, the 
server or both?

Then some explanations:
- on line 922, if the server has received some CP1252 text, it should 
default to $GLOBALS['xmlrpc_defencoding']='UTF-8'. Did you also change 
that variable? otherwise I cannot explain it...
- are you using php 4 or 5? there are some differences between the xml 
parser use by php
- there is some more work surely to be done for everything to work fine. 
Setting internalencoding to CP1252 before emitting (encoding) data is 
fine, but, as you have seen, it cannot be used when decoding it. And 
both server and client decode data (request and response, respectively). 
Since cp1252 is not supported by the php4 xml parser, we have to find 
some workaround
