Kohana 3: транслитерация кириллицы

Kohana уже доросла до версии 3.3, а проблема с транслитерацией кириллицы тянется уже довольно давно.

Использую следующие костыли/надстройки для решения этой проблемы.

В 'APPPATH/classes' создаём скрипт 'utf8.php' со следующим содержимым:

<?php defined('SYSPATH') OR die('No direct script access.');
class UTF8 extends Kohana_UTF8 {

 /**
  * @var  boolean  Does the server support UTF-8 natively?
  */
 public static $server_utf8 = NULL;

 /**
  * @var  array  List of called methods that have had their required file included.
  */
 public static $called = array();


 /**
  * Replaces special/accented UTF-8 characters by ASCII-7 "equivalents".
  *
  *     $ascii = UTF8::transliterate_to_ascii($utf8);
  *
  * @author  Andreas Gohr <andi@splitbrain.org>
  * @param   string   $str
  * @param   integer  $case
  * @return  string
  */
 public static function transliterate_to_ascii($str, $case = 0)
 {
  if ( ! isset(self::$called[__FUNCTION__]))
  {
   require APPPATH.'utf8'.DIRECTORY_SEPARATOR.__FUNCTION__.EXT;

   // Function has been called
   self::$called[__FUNCTION__] = TRUE;
  }

  return _transliterate_to_ascii($str, $case);
 }
}

В каталоге 'APPPATH' создадим каталог 'utf8' и поместим в него скрипт 'transliterate_to_ascii.php' со следующим содержимым:

<?php defined('SYSPATH') or die('No direct script access.');

P.S. Под 'APPPATH' подразумеваю константу APPPATH определяемую в index.php:

define('APPPATH', realpath($application).DIRECTORY_SEPARATOR);
