I doubt that we should constrain or expect applications to use any 
particular internal representation for characters.   If we expect them 
for instance to use UTF-8, they may then need to do multiple 
conversions, e.g.

input format -> UTF-8 -> RACE
RACE -> UTF-8 -> output format

which hardly seems desirable.
