How to convert UTF-8 to XML entities?

[Siegfried Heintze (Aditi)]

I did a little google searching and found 
http://perl-xml.sourceforge.net/faq/#encoding_conversion. This does not look 
like it would work for multi-byte Chinese characters.

Does anyone have some perl (or emacs lisp) code that will convert the UTF-8 
chinese text in my XML file to entities that look like this: 安?

Thanks!
