Anti spam find only letters and numbers in string - iDark - 12.06.2017

Hello,

I want to make an anti spam that detects only letters and numbers not any other characters.
If I type "hello", when I try to type "hello.?" or other characters except letters or numbers to find it as "hello".
I need to use regex to do this or there is another way?

Thanks!
