I think, Eli is afraid of the following sort of inconsistency

(string-collate-lessp "z" "ö" "de_DE.UTF-8") ; => nil
(string-collate-lessp "z" "ö" "sv_SE.UTF-8") ; => t

Mixed language example: U+0049 LATIN CAPITAL LETTER I vs. U+0406 
CYRILLIC CAPITAL LETTER BYELORUSSIAN-UKRAINIAN I

(sort '("Івана" "Ivan" "Термін" "Вони")
       (lambda (a b) (string-collate-lessp a b "uk_UA.UTF-8")))
("Вони" "Івана" "Термін" "Ivan")

(sort '("Івана" "Ivan" "Термін" "Вони")
       (lambda (a b) (string-collate-lessp a b "en_US.UTF-8")))
("Ivan" "Вони" "Івана" "Термін")

I suppose users should get result native to their languages even though 
others may get another order.
