Also, the problem we're dealing with here is mainly lack of
standardization of the encoding part of locale names. AFAIK, just about
everybody agrees on "es_ES", "ru_RU", etc; it's the part that comes
after that (if any) that is not too consistent across platforms.
So I see no problem in distinguishing between pt_PT and pt_BR if it
turns out we have to. The trick is to not look at any more of the
locale name than that; and if we standardize on "stopword files are
UTF8" then I don't think we need to.
