  key will be in UTF-8 , UTF-8 supports the full Unicode
set, though XML
only allows a subset.

Read http://xmlsoft.org/e
ncoding.html

  I guess wprintf does not expect UTF-8 encoding.

  Since UTF-8 and ASCII coincide for the ASCII subset of
Unicode, I don't
know what you're doing to print them, but you really have a
problem.
Being sure to understand the difference between, unicode,
code points,
encoding is really a requirement for any programmer those
days

Read also the other article pointed from Tim Bray, he tries
to give 
explanations around those issues.
