Sorry, I wasn't clear (and my memory was a bit loose).

The Standard says:

       An implementation may allow  multibyte
       characters  that  are not part of the basic source character
       set to appear in identifiers;  which  characters  and  their
       correspondence    to    universal    character    names   is
       implementation-defined.

An implementation *must* accept:

    int x\u00E1n;

It *may* accept:

    int xán;

and, if it does, the two names must [*] be interchangeable.

[*] Absent a level of language-lawyering that you really don't want to know
about.
