Drats, I knew I should have taken latin : )

Just tack on 4 chars to my solution, \200 is the first 8 bit ASCII char, so that is what I'll have to use:

sub c {                             
($_,$a,%h)=@_;s!.!$h{$&}||=($a=~/./g,"$&\200")!sge;y/\200//d;$_
}

Update: Chipmunk seemed to think this needed to work : ) so it's fixed above, but doesn't come close to competing.
