Inline validation for special characters onchange()

Inline validation for special characters onchange()

I am using jQuery inline validation ( https://github.com/posabsolute/jQuery-Validation-Engine) and it's awesome.  I would like to have it validate after each character (onchange) for special characters.  If one is typed, erase it, and pop up the validation message box.  I haven't found anything searching.  Has anyone already created this?
