Print every character your program doesn't have

It's fun to see a rule bypass or two, but almost of those were hacks and not technically very impressive.

Kudos to the Whitespace one though, pretty cool.

Coffee-Script: 82

(f=(f)->console.log(String.fromCharCode(c)) for c in [20..126] if c !in f)("\\\""+f)

Hopefully translation to JS doesn't kill the set of characters used in the source.

Javascript: 93

(f=function(f){for(u=20;u<127;u++){if(f.indexOf(u)<0)alert(String.fromCharCode(u))}})('\\\''+f)

Just submitted my version. I think I cannot be beaten in numbers of characters... [1]
