Extra Name Characters.

[8Ball]

So I was randomly looking through the sa-mp masters list, when I came across "crazy bobs cops & robbers" and I was looking through the player list and seen people with characters in there name like "()" "." "=" "{}" etc etc, and most of the characters that were implented in 0.1b.
Is there any such thing as a plugin or filterscript to enable more characters for use in names. I don't really know how it could benefit the server, but it'd be cool too have something extra to put in your name or changing a clantag, i know many old clantags were different like (UvH) for example.
Danks.
