ID: 44014 Updated by: hirokawa@php.net Reported By: michael202 at gmx dot de -Status: Assigned +Status: Feedback Bug Type: mbstring related Operating System: Win XP PHP Version: 5.2.5 Assigned To: hirokawa New Comment: BOM of Unicode is not supported by encoding conversion function in mbstring. And big endian is default in UTF-16. Please specify 'UTF-16LE' if you need to specify little endian format. Try, <?php $utf16 = chr(0).chr(0x4d).chr(0).chr(0x6f); //'Mo' $utf8 = mb_convert_encoding($utf16, 'UTF-8', 'UTF-16'); echo($utf8 . "\n"); // -> Mo ?> or <?php $utf16 = chr(0x4d).chr(0).chr(0x6f).chr(0); //'Mo' $utf8 = mb_convert_encoding($utf16, 'UTF-8', 'UTF-16LE'); echo($utf8 . "\n"); // -> Mo ?> Previous Comments: ------------------------------------------------------------------------ [2008-02-05 05:10:37] jani@php.net Assigned to the mbstring maintainer. ------------------------------------------------------------------------ [2008-02-01 12:08:07] michael202 at gmx dot de Description: ------------ mb_convert_encoding 'destroys' first character when converting from UTF16 to UTF8 (iconv works). Reproduce code: --------------- $utf16 = chr(0xFF).chr(0xFE).chr(0x4d).chr(0).chr(0x6f).chr(0); //'Mo' $utf8 = mb_convert_encoding($utf16, 'UTF-8', 'UTF-16'); echo($utf8 . "\n"); // -> ´++´¢ìo $utf8 = iconv('UTF-16', 'UTF-8', $utf16); echo($utf8 . "\n"); // -> Mo Expected result: ---------------- mb: (BOM8)Mo iconv: Mo (BOM8) is a placeholder Actual result: -------------- mb: (BOM8)´¢ìo (copied from cmd shell) iconv: Mo (BOM8) is a placeholder ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44014&edit=1
