Comment (by guillep2k):

 By RFC 3987 (http://tools.ietf.org/html/rfc3987#section-2.1), the unicode
 characters outside the US-ASCII repertoire are not reserved, and therefore
 cannot be used for syntactical purposes. This should make them suitable
 for any URL and shouldn't pose a security problem (at least I hope so!).

 I don't see how Wordpress can process these characters if it's not set up
 for using UTF-8, but anyway here's a patch. It should be thoroughly
 tested, though, because I had to modify the make_clickable() presentation
 filter as well (used to filter comment_text when displaying comments).
