However, that is not necessarily true, so the statement should be changed appropriately. Test script: --------------- var_dump(preg_match('/^[[:alnum:]]$/u', "\xc3\x84")); Expected result: ---------------- int(0) // expected according to the current documentation Actual result: -------------- int(1) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67041&edit=1
