Subject: remove all illegal chars form string

Hi,

Is there a simple way to remove all but the legal chars from a string.  where the legal chars are for example: a-z A-Z 0-9
So everything should be removed from the string but these characters.
"exam@p  Le3|�" --> "exampLe"

I don't know very much about regular expressions, so I don't know if it's possible with sub or gsub.  My first Idea was to loop over the string and check every character but I wondered if there is something more simple or better.

Thanks
