The mb_ series functions have errors when handling UTF-16LE and UTF-16BE character encodings! For example:
<?php $utf8_str="这是一个测试"; $iconv_utf16=iconv('UTF-8', 'UTF-16LE', $utf8_str); echo "iconv_to_UTF-16: ".base64_encode($iconv_utf16).PHP_EOL; $mb_utf16 = mb_convert_encoding($utf8_str, 'UTF-16LE','UTF-8'); echo "mb_xx_to_UTF-16: ".base64_encode($mb_utf16).PHP_EOL;
Native PHP execution results:
iconv_to_UTF-16: 2Y8vZgBOKk5LbdWL mb_xx_to_UTF-16: 2Y8vZgBOKk5LbdWL
Peachpie execution results:
iconv_to_UTF-16: 2Y8vZgBOKk5LbdWL mb_xx_to_UTF-16: 6L+Z5piv5LiA5Liq5rWL6K+V
