In ruby, there is a variable called $KCODE.  If you set it to "UTF-8" 
(or just "U"), then it makes regular expressions match characters rather 
than single bytes.   If you set $KCODE to "N" (the default), then 
regular expressions will match single bytes (unless you use the /u flag 
on your regular expression).

You can set $KCODE from the command line, e.g. -Ku or -Kn.
