Username Regular Expression

[محروم.كوم]

Hello, I am trying to limit "Username Regular Expression" in my vBulletin so bots or who ever cant register with certain characters.


I found a post here that has what I wanted but doesn't allot |()-_

Basically I want them to be able to register with a-z, 0-9 and be able to use !@#$%^&*(()_+ but NOT "è??û" kind of characters.

Think anyone's got an idea? __DEFINE_LIKE_SHARE__
