标签: php utf-8 utf-16

我有来自strace的以下输出,我想使用PHP将其转换为UTF-8:

R\00f6dhakev\00e4gen 4
R\00e4ntm\00e4starv\00e4gen 24
K\00d8BENHAVN

以上字符串是我认为的UTF 16 HEX。

发现以下功能有效:

function utf8_urldecode($str) {

  $str = str_replace("\\00", "%u00", $str);

  $str = preg_replace("/%u([0-9a-f]{3,4})/i","&#x\\1;",urldecode($str));

  return html_entity_decode($str,null,'UTF-8');

}

试试这个:

function masked_utf16_to_utf8($str) {
    $str = preg_replace_callback('/\\\\([0-9A-Fa-f]{2})([0-9A-Fa-f]{2})/', create_function('$match', 'return mb_convert_encoding(chr(hexdec("$match[1]")).chr(hexdec("$match[2]")), "UTF-8", "UTF-16");');
    return $str;
}
