 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}/
