Feature #2350: Unicode specific functionality on String in 1.9
http://redmine.ruby-lang.org/issues/show/2350

Author: Manfred Stienstra
Status: Open, Priority: Normal

I was wondering is there are any plans to include Unicode aware methods for Unicode encodings on String? For example, upcase and downcase only handle ASCII characters at the moment.

cafe = "Café"
cafe.encoding # => #<Encoding:UTF-8>
"Café".upcase # => CAFé
