In my opinion, the only sensible role for characters
in a Unicode-enabled world is that they ought to be
strings of length one.

I think that the standard should permit (and possibly
even require)

(string? #/a) ==> #t

and that all string functions should work on
characters. char-upcase, char-downcase, and
char-foldcase should, as Per says, be deprecated.

Additionally, so should all procedures that
require character arguments but duplicate
functionality available from other procedures
that take string arguments in their place.
