That could well be so, yes.  But even for such a partial solution, we
still need gobs of infrastructure we don't have.  For example, people
mentioned language-dependent character folding: to be able to do that
we need a large language-dependent database of collation data.  That
probably means import or access the Unicode CLRD
(http://cldr.unicode.org/).  (We could instead rely on the underlying
libc to provide that, but then it would only work on glibc-based
systems, and will require to switch locales each time we need another
language, which is IMO cumbersome, inefficient, and inelegant.)  We
cannot seriously speak about language-dependent processing before we
have that data and functions to use it.

Having that infrastructure is also necessary for more sophisticated
language-sensitive processing that I think we should eventually have,
so patches to add such a functionality are welcome.
