Finnish people quite often find it easier to spell their name without the umlauts when appearing online. The situation used to be much worse when email headers and BBS usernames were still ASCII-only (before Unicode), but you still occasionally run into problems. Most recently, I've had trouble using a street address with umlauts for Amazon AWS billing. Bad web apps tend to convert the umlauts into HTML entities and then recursively escape those entities with &s when editing data or resubmitting forms.
