Can you point me to the place of the XML encoding rules? After a short look into the spec I didn't find something which applies to XML input encoding.
AFAIK it's possible to teach libxml2 additional encodings.

That's something I'd like to do, but I need some time when I can do it. ;-) My first step was to improve the performance of libxml2 -> WebKit.
