>> %w[Xeo xeo ball ABC abc].sort.each{|word| p word => word.unpack('C*') }
{"ABC"=>[65, 66, 67]}
{"Xeo"=>[88, 101, 111]}
{"abc"=>[97, 98, 99]}
{"ball"=>[98, 97, 108, 108]}
{"xeo"=>[120, 101, 111]}
=> ["ABC", "Xeo", "abc", "ball", "xeo"]

There is always a way to make things work on both, it's just that I
don't care much about 1.8 anymore.
