Ruby: upcase for Cyrillic

Question

ruby

In Ruby 1.9.2, the upcase and downcase methods have no effect on the Cyrillic alphabet.
Are there any solutions to the problem?

Answer 1

We put the unicode gem github.com/blackwinter/unicode
and connect it to our project require "unicode";
and use its Unicode::downcase and Unicode::upcase methods
. I just extended the standard String class: pastebin.com/8ntg0sjK
I have written more on my blog and described how to use it with Ruby on Rails.
Link to the blog in the profile or write in a personal. I'm afraid of the habraeffect :)

Answer 2

Working option, thanks.
