"non-ascii characters in c" Code Answer


c90 doesn't allow additional character in identifier (over those in the basic characters set), c99 do (both with the universal character syntax -- uxxxx and uxxxxxxxx -- and an implementation defined set of other characters). in c99:

    identifier identifier-nondigit
    identifier digit
    other implementation-defined characters
nondigit: one of
    _ a b c d e f g h i j k l m
    n o p q r s t u v w x y z
    a b c d e f g h i j k l m
    n o p q r s t u v w x y z
digit: one of
    0 1 2 3 4 5 6 7 8 9

i don't know how well it is supported by c implementations, i know that plan9 c compiler could handle other characters before it was standardized.
