I found tips in the stackoverflow.

http://stackoverflow.com/questions/2934563/how-to-decode-unicode-escape-sequences-like-u00ed-to-proper-utf-8-encoded-cha

I try it.

<?php
$str = "\u3053\u3093\u306b\u3061\u306f\u30ef\u30fc\u30c9";

function replace_unicode_escape_sequence($match) {
    return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UCS-2BE');
}
$str = preg_replace_callback('/\\\\u([0-9a-f]{4})/i',
                             'replace_unicode_escape_sequence', $str);
var_dump($str);


Then it displays:
string(24) ""

regards,
