Comment (by nbachiyski):

 For me, `array_search( 'CP1251', mb_list_encodings() );` returns `false`
 (PHP 5.4.39). The canonical `mb_` encoding name is `Windows-1251`. Even
 though `mb_convert_encoding( 'baba', 'CP1251', 'CP1251' );` works
 properly, our support-encoding checks will be bypassed, so we should use
 the canonical name.
