Diacritics aren't any problem. If you don't want to do code, just copy paste any of these in the page title. Squared is also not a problem. Just find a wikipedia page that has it and copy paste.

The only thing you shouldn't use is # or any bracket, or start with a period (or two. Three is fine) or colon. There used to be times & was off-limits as it broke the url, but that's fixed now. There's also a lenght retriction.

I'm also on an off-wikia Tolkien wiki, and the policy towards diacritics we have there is we create a redirect without the accents to accomodate searches. That would solve the also problem Robin noted.

If there are diacritics you use a lot, consider adding them to your wiki's MediaWiki:Edittools.
