/**
* A PHP port of URLify.js from the Django project
* (https://github.com/django/django/blob/master/django/contrib/admin/static/admin/js/urlify.js).
* Handles symbols from Latin languages, Greek, Turkish, Russian, Ukrainian,
* Czech, Polish, and Latvian. Symbols it cannot transliterate
* it will simply omit.
*
* Usage:
*
* echo URLify::filter (' J\'étudie le français ');
* // "jetudie-le-francais"
*
* echo URLify::filter ('Lo siento, no hablo español.');
* // "lo-siento-no-hablo-espanol"
