Note Submitter: laurynas dot butkus at gmail dot com ---- In PHP4 html_entity_decode() is not working well with UTF-8 spitting: "Warning: cannot yet handle MBCS in html_entity_decode()!". This is working solution combining several workarounds: <?php function html_entity_decode_utf8($string) { static $trans_tbl; // replace numeric entities $string = preg_replace('~&#x([0-9a-f]+);~ei', 'code2utf(hexdec("\\1"))', $string); $string = preg_replace('~&#([0-9]+);~e', 'code2utf(\\1)', $string); // replace literal entities if (!isset($trans_tbl)) { $trans_tbl = array(); foreach (get_html_translation_table(HTML_ENTITIES) as $val=>$key) $trans_tbl[$key] = utf8_encode($val); } return strtr($string, $trans_tbl); } // Returns the utf string corresponding to the unicode value (from php.net, courtesy - romans@void.lv) function code2utf($num) { if ($num < 128) return chr($num); if ($num < 2048) return chr(($num >> 6) + 192) . chr(($num & 63) + 128); if ($num < 65536) return chr(($num >> 12) + 224) . chr((($num >> 6) & 63) + 128) . chr(($num & 63) + 128); if ($num < 2097152) return chr(($num >> 18) + 240) . chr((($num >> 12) & 63) + 128) . chr((($num >> 6) & 63) + 128) . chr(($num & 63) + 128); return ''; } ?>
