finding character code from string

Hullo,

This has probably been asked before, but are there any plans
for adding an EXSLT function for retrieving the Unicode character
code of a character (i.e., a string of length 1)?

Something like this perhaps:  str:character-code('a')


   cheers,
      geoff
