Note that this capability is largely already there, and already
used in XFree86 builds. The only thing that might be getting
duplicated now is Unicode and code conversion tables, but replacing
that with iconv() is not particularly easy, and definitely not
particularly portable. (I'm not sure *BSD even have iconv() support
yet; the names of character sets for iconv aren't at all portable
across systems.)
