Actually, the ISO WG9 (working group on Ada) has now allowed
Standard.Character to be Latin-1 rather than ASCII (ISO-646)
in Ada 83 compilers. As Mark implies, this will be required for Ada 9X.
Furthermore, Ada 9X will have a "Wide_Character"
(and Wide_String) in Standard corresponding to the 16-bit
Basic Multilingual Plane (BMP) of ISO 10646, otherwise known as Unicode.
Any Unicode character is permitted in comments (in fact, any character at
all is permitted in comments if you can get your compiler to swallow it,
though some characters might reduce portability of the source (or
at least its representation)).
We are also considering allowing some of the BMP/Unicode
characters in identifiers, either for all
compilers, or as a localization option. This last part is still somewhat
up in the air, given the relatively recent approval of ISO 10646,
and the somewhat confliciting concerns of localization and portability.
