The "flair" link in the profiles for people with all-Unicode usernames is broken.
What's happening here is that the flair link is
http://site.stackexchange.com/users/<userid>/<username slug>/flair. For such usernames, the slug is blank, which leads to
http://site.stackexchange.com/users/<userid>//flair, which is just a link to the profile.
Could this be fixed? To fix it, we could either have the system recognize the double-slash, or remove the slug from the flair link (I don't see why it's needed).
