I’ve had a look at the tables, and the users in question had their ‘user_nicename’ as their name WITH the weird characters. However this still only seems to affect the users links in the forum topic view and nowhere else on the site.

It would be good if there could be some sort of clean up process when storing the username in the first place to remove any non alpha characters.

I have modified the ‘user_nicename’ manually in phpmyadmin and it has resolved the issue for that one user. Obviously this is not an ideal solution though, even though it is rare that any usernames from Facebook do contain weird characters.

Thanks for your input
