  When you use libxml2 API you must pass only UTF-8 strings when there
is an xmlChar *, if you don't you may see the kind of behaviour you are
seeing.

Either those XMPP applications don't use an XML parser to parse XML, or
you made a mistake when using libxml2 made it convert it to that string.
Make sure you are saving to UTF-8 when talking to XMPP too.

paphio:~/XML -> cat tst.xml
<foo attr="&#x422;&#x415;&#x43C;&#x44B;&#x447;"/>
paphio:~/XML -> xmllint tst.xml
<?xml version="1.0"?>
<foo attr="&#x422;&#x415;&#x43C;&#x44B;&#x447;"/>
paphio:~/XML -> xmllint --encode UTF-8 tst.xml
<?xml version="1.0" encoding="UTF-8"?>
<foo attr="ÐÐÐÑÑ"/>
paphio:~/XML ->
