I absolutely love strange unicode strings. It's handy if you ever want to find out what a server's running. One time, I put a bunch of emoji's in a GET param of a Google site, then got a big Java error page. I had no idea Google ran Java. Edit: Another one that tends to be fun is [] in the param, like http://example.com/?get[]=[] http://example.com/?get[]=[]. And you can things inside, like http://example.com/?get['"%05<!]=[%FE%FF] http://example.com/?get['"%05<!]=[%FE%FF]
