This library provides method to transliterate Unicode characters to an ASCII approximation.

The functionality in this library was originally written by Russel Norris for his Stringex library. This gem is an extraction of the Unicode transliteration functionality from Stringex into a separate library.

The Unidecoder component of Stringex is itself a port of Sean M. Burke's Unidecode Perl module.
