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.
