Ruby 1.8 does not have multi-byte character support built in, so it 
assumes each character is one byte. If you would like unicode support, 
include in your scripts

$KCODE='u'
require 'jcode'

Then chop will work properly. (Though I'm not sure everything will be 
perfect)

Ruby 1.9 has unicode support built in and handles this properly out of 
the box.
