"Editing [[Pikku-Vesijärvi]] I noticed that VE's suggested DEFAULTSORT was exactly the title. VE should be set to drop the diacriticals when suggesting DEFAULTSORT - should have been "Pikku-Vesijarvi" with a plain "a"."
Looking at some other wikis it seems some do use diacritics in DEFAULTSORT (at least the Czech and Estonian ones do at [[cs:Édith Piaf]] and [[et:Édith Piaf]) so this seems like something that should be configurable based on each wiki's policy.
