Converting string to Unicode

[Desilets, Alain]

I am working on an Emacs mode for programming by voice (i.e. dictating computer 
code using speech recognition system):

http://voicecode.iit.nrc.ca/

This mode communicates with the speech recognition engine (an application 
outside of Emacs) through XML messages over socket connections.

In particular, whenever a new character is typed into Emacs, Emacs sends an XML 
message to the SR system to notify it. This XML message contains the character 
that was typed as well as the name of the buffer and the position where it was 
typed.

Whenever I typed an accented character in Emacs, the XML message that gets 
generated turns out to be malformed, because the character that was typed is 
inserted into the XML message as a byte sequence that uses the original 
encoding of that character in the buffer, as opposed to the unicode encoding 
that the XML message is supposed to be encoded with.

So my question is this. What would be the easiest way for me to take a 
character that was inserted into an Emacs buffer, and turn it into a unicode 
character to be inserted in the XML message?

Thx
