That was the idea behind the "character_set_traits" class in the current
prototype. You could just implement the tratis for some other encoding,
and you'd be set. The problem though (and in my opinion it's a big one),
is that for the encoded_string class (and any iostream implementation
based on the same concepts) to be useable at all as a Unicode string
class, we would have to include a lot of functionality that is Unicode
specific. (Normalization is one example) What would we do with this
functionality for Shift-JIS?
