ASIS 99 currently returns identifiers in Wide_Strings. That is enough to
handle all possible Ada 95 programs. I suspect that the problem is in the
XML conversion tool not handling Wide_Characters properly and not with ASIS.
(Or just as likely, the XML processing tools not handling UTF-8 properly.)

I suspect that the new version of ASIS will provide an option to get
identifiers in Wide_Wide_Strings.

In any case, one of the big advantages of using ASIS over writing your own
parser is that the resulting program is independent of the character set
used. So it works with anything supported by your compiler vendor (and still
does if you change vendors). ASIS code that depends on the input source
representation (which is not defined by Ada anyway) is probably broken. And
there is no chance of any sort of agreement on source representations for
ASIS (or even the naming of them) if there isn't be any for Ada.
