Cool, good news, the Fingertips’ ActiveSupport::Multibyte is checked into Rails. This equips every string with a chars method which offers a host of friendly Unicode-aware methods for the string. You know: reverse, length, slice and the like.

 name = 'Claus M��ller'
 name.reverse #=> "rell??M sualC" 
 name.length #=> 13
 name.chars.reverse.to_s #=> "rell��M sualC" 
 name.chars.length #=> 12

This is valuable, essential work. Thanks to Thijs, Manfred, Julik and related contributors. Along with Nikolai’s work, we’re on our way.
