You might want to strip \n and \r(from usernames/aliases) when people register. Stripping everything from 00-1f should probably be safe, too.

Good idea, I'll make it strip 0-31 127-159 character list from the user names.

Using ctype_print http://www.php.net/ctype_print where available might be a better idea, still.

Stripping out 0-31 probably won't mess with very many foreign character-coding schemes(well, not the well-designed ones at least), but if you strip out anything in 128+, you might have a problem.

I'll run some tests and see how well ctype_print works.

Can't use that function, because it is not always avaliable.

Also the ctype_print() only checks the given data, the actual code removes the invalid characters.
