"exam@p Le3|�".gsub(/\W/, '') 

will return

 "exampLe3"

I strongly suggest you learn about regular expressions. You can start here, 
http://en.wikipedia.org/wiki/Regular_expression , there are many links to 
many tutorials. Here, http://www.rubycentral.com/book/tut_stdtypes.html , you 
can find info on ruby regular expressions ; though it might be best to get 
yourself a Ruby book.
