That actually only shows up as a "question mark" because either your  
browser or ruby-forum.com wasn't all that bright. It was actually an  
emdash. Anyway since this is for urls, you are ok as far as domain  
names go, because they only allow alphanumeric characters and  
hyphens. As far as stuff after the slash goes though, that could be  
open game, I'm not sure what the rules are.
