You're trying something completely wrong here. The ? is only a compiler 
thing and not an operator. If you write ?letter, it's wrong because ?l 
can be interpreted as the code of the letter l, and the remaining etter 
is rubbish. It is not a real operator!

Apart from that, your each doesn't split the string into letters, but 
into lines.

In Ruby 1.8 if you want the code of n-th character of your str, just 
write str[n]. It doesn't return a single character, but its code.

In Ruby 1.9 str[n] returns n-th character in the form of a short string, 
and to get code of n-th letter, write str[n].ord.

TPR.
