No. When I mentioned Wide_Wide_String I meant an array of code points. The
logical view of *any* string type is array of code points. The only
difference between different string types is in the constraints put on the
code points. E.g. String has code points 0 to 255. IBM_437_String would
have a non-contiguous set of code points etc.

I don't see how generics are relevant here. All strings are arrays of code
points. They all belong to this class. No explicit conversions should be
needed between them.

No idea what this is supposed to mean.
