In fact, I'm afraid we have a problem, because the `is' functions from
<ctype.h> are fully locale-dependent.  Thus, they don't only depend on
the charset being used but also on the language settings, which makes
them unsuitable for the implementation of `char-set:letter' (because it
should contain _all_ the letters representable with the current charset,
not only those of some particular language).

I'm not an expert in that domain, but the SRFI seemed to imply that the
notion of a letter is pretty well defined in Unicode (which is fortunate
because all the people using the various scripts do know what a letter
is in their script ;-)).
