Subject: [ruby-core:30540] [Bug #3376] russian support

Bug #3376: russian support
http://redmine.ruby-lang.org/issues/show/3376

Author: Yury Korolev
Status: Open, Priority: Normal
Category: M17N, Target version: 1.9.2
ruby -v: ruby 1.9.2dev (2010-05-31 revision 28117) [x86_64-darwin10.3.0]

1. String#upcase/String#downcase don't work with russian characters

ruby-1.9.2-preview3 > "������������".upcase
 => "������������" 
ruby-1.9.2-preview3 > "������������".downcase
 => "������������" 

2. Regex doesn't work with POSIX bracket classes

ruby-1.9.2-preview3 > "������������" =~ /[:alpha:]/
 => nil 

It's working with unicode groups

ruby-1.9.2-preview3 > "������������" =~ /\p{L}/
 => 0 

3. Negated unicode groups don't work

SyntaxError: (irb):13: invalid character property name {L}: /\P{L}/
