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) =\> “Ä°”

UnicodeUtils.nfkc(“fi”) =\> “fi”

Online documentation: [http://unicode-utils.rubyforge.org](http://unicode-utils.rubyforge.org)  
Source: [GitHub - lang/unicode\_utils: Unicode algorithms for Ruby 1.9](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 “â„«” ANGSTROM SIGN utf8:e2,84,ab\>]

I do not doubt it is full of very interesting information but I’d love  
to  
it… Base64 encoding for news articles is not nice, not everybody use a  
web  
browser to read/post articles, thanks.
