如何在PHP 5.6中使用utf-8字符获取文件列表？

I am Vietnamese and I want to use PHP to get a list of files in a directory that uses utf-8 characters.

My hope output is an array of files: array("music/Nhạc Thiền Tĩnh Tâm 1.mp3","music/Nhạc Thiền Tĩnh Tâm 2.mp3","music/Nhạc Thiền Tĩnh Tâm 3.mp3","...");

My code:

<?php
foreach (glob("music/*.mp3") as $ds) {
    echo $ds . "<br>";
}

I use the glob() function.My hope output is an array of files: array("music/Nhạc Thiền Tĩnh Tâm 1.mp3","music/Nhạc Thiền Tĩnh Tâm 2.mp3","music/Nhạc Thiền Tĩnh Tâm 3.mp3","..."); But the return list is an empty array. How can I do that in PHP 5.6 on Windows? Please help me!
