I would guess most systems that need that, have functions in system
libraries that can be easily interfaced. The bigger problem is the fact
that character is theoritically Latin-1, which even if you have converters
is going to only completely map if you're converting to Unicode or Latin-1
(I believe there's an EBCDIC standard whose character set is the same as
Latin-1.)

Yes. Check out the Ada standard or a good Ada book for more details.
(The main catch being that Wide_Character only encodes the BMP, and
defines the block of surrogate characters as graphic.)
