Subject: Multibyte regexps...



I am having some issues with regular expressions when working with japanese 
strings.

Using ruby-1.8.3 on Windows XP home (Japanese version) I have this test:

irb(main):271:0> s = "鞄"
=> "\212\223"
irb(main):272:0> l = "行"
=> "\215s"
irb(main):273:0> l =~ /s/
=> 1
irb(main):274:0> puts "#{$`}<<#{$&}>>#{$'}"
E<s>>
=> nil
irb(main):275:0> "#{$`}<<#{$&}>>#{$'}"
=> "\215<<s>>"
irb(main):276:0> s =~ /l/
=> nil


As you can see comparing two totally different characters (kanji) gives me a 
match. Reversing the match gives nil.


How can I get ruby to match things correctly??
