UnicodeUtils is a pure Ruby library that implements
Unicode algorithms for Ruby 1.9.

Install with RubyGems:

  $ gem install unicode_utils

Example code:

  require "unicode_utils"

  UnicodeUtils.upcase("i", :tr) => ""

  UnicodeUtils.nfkc("") => "fi"

Online documentation: http://unicode-utils.rubyforge.org
Source: http://github.com/lang/unicode_utils

New since the 0.4.0 release:

 * The name method was renamed to char_name because it
   conflicted with Module#name.

 * Case-folding

 * A grep method to search through the Unicode character
   database and "U" as a shortcut for use in irb:

  $ irb -r unicode_utils/u
  irb(main):001:0> U.grep /angstrom/
  => [#<U+212B "Άς" ANGSTROM SIGN utf8:e2,84,ab>]
