Function setlocale, reports that encoding is setted to desired. But case conversion make no changes or change letters incorrectly (results may vary). Reproduce code: --------------- <?php header('Content-type: text/html; charset=utf-8'); $sL = 'àáâãäå¸æçèéêëìíîïðñòóôõö÷øùúûüýþÿ'; // lower russian alphabet, source file must be in utf-8 encoding $sU = 'ÀÁÂÃÄŨÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞß'; // upper russian alphabet echo setlocale(LC_ALL, 'ru_RU.UTF-8') .'<br>'; echo 'Lower to upper:<br>'; echo strtoupper($sL) .'<br>'; // incorrect result echo mb_strtoupper($sL, 'utf-8') .'<br>'; // correct result, for comparsion echo 'Upper to lower:<br>'; echo strtolower($sU) .'<br>'; // incorrect result echo mb_strtolower($sU, 'utf-8') .'<br>'; // correct result, for comparsion ?> Expected result: ---------------- ru_RU.UTF-8 Lower to upper: ÀÁÂÃÄŨÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞß ÀÁÂÃÄŨÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞß Upper to lower: àáâãäå¸æçèéêëìíîïðñòóôõö÷øùúûüýþÿ àáâãäå¸æçèéêëìíîïðñòóôõö÷øùúûüýþÿ Actual result: -------------- ru_RU.UTF-8 Lower to upper: àáâãä̸æçèéêëìíîïðñòóôõö÷øùúûüýþÿ ÀÁÂÃÄŨÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞß Upper to lower: &#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533; àáâãäå¸æçèéêëìíîïðñòóôõö÷øùúûüýþÿ ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46402&edit=1
