 Hi Robert

 I use JTR with OS X, my wordlist, my terminal, my hashlist are UTF-8 
encoded, all hashes are found, even password with special local letters 
such as "é" "è" "ô" etc...
 If you use incremental mode (-i:) with special letter you have to 
modify params.h (check old post from this list for more info) and 
generate a new charset .
