Comment(by Denis-de-Bernardy):

 Their implementation is in classes/core/String.inc.php, and goes like
 this:

 {{{
 function html2utf($str) {
         // convert named entities to numeric entities
         $str = strtr($str, String::getHTMLEntities());

         // use PCRE-aware replace function to replace numeric entities
         $str = String::regexp_replace('~&#x([0-9a-f]+);~ei',
 'String::code2utf(hexdec("\\1"))', $str);
         $str = String::regexp_replace('~&#([0-9]+);~e',
 'String::code2utf(\\1)', $str);

         return $str;
  }
 }}}

 Side note: best I'm aware, strtr is not mb safe, so the above code is
 potentially buggy in mb languages.
