/**
* Unidecode takes UTF-8 data and tries to represent it in US-ASCII characters (i.e., the universally displayable characters between 0x00 and 0x7F).
* The representation is almost always an attempt at transliteration -- i.e., conveying, in Roman letters, the pronunciation expressed by the text in
* some other writing system.
*
* The tables used (in data) are converted from the tables provided in the perl library Text::Unidecode (http://search.cpan.org/dist/Text-Unidecode/lib/Text/Unidecode.pm)
* and are distributed under the perl license
*
* @author Francois-Guillaume Ribreau
*
* Based on the port of unidecode for php
