characters

What's an efficient way of checking if a username contains a number of special characters that I define.

Examples: % # ^ . ! @ & ( ) + / " ? ` ~ < > { } [ ] | = - ;

I need to detect them and return a boolean, not just strip them out.

Probably a super easy question but I need a better way of doing this than a huge list of conditionals or a sloppy loop.
