Hello,

What is the proper way to read a directory such that file names are not
garbled? Here is the example I borrowed form the std.file documentation.
Screen shots of folder is attached. Thanks.

void main(string[] args)
{
        bool callback(DirEntry* de)
        {
                if (de.isfile)
                        mciPlay(toUTF8(de.name));
                return true;
        }

        listdir("snd",&callback);
}

D:\code>play
snd\american.ogg
snd\bigdog.flac
snd\blackmail.mp3
snd\ding.wav
snd\kam.aif.aiff
snd\豺｡縺・ogg

Much appreciate the info. I'm not however interested in outputting to 
the console. I'm trying to call mciSendString with the name of each file 
contained in the directory. The process fails however, when it 
encounters a Japanese file name. Please see code below. Any idea what 
I'm doing wrong?

import std.file;
import std.string : cstring = toStringz;
import std.c.windows.windows;

pragma(lib, "winmm.lib" );

extern(Windows) {
        uint mciSendStringW(
                LPCWSTR lpszCommand,
                LPWSTR lpszReturnString,
                uint cchReturn,
                HANDLE hwndCallback);
}

void main(string[] args)
{
        bool callback(DirEntry* de)
        {
                if (de.isfile)
                        mciPlay(de.name);
                return true;
        }

        listdir("snd", &callback);
}

void mciPlay(string audio)
{
        uint mciSendString(string s)
        {
		return mciSendStringW( cast(LPCWSTR)s, cast(LPWSTR)null, 0, 
cast(HANDLE)0 );
        }

	auto exists = mciSendString(`open "` ~ audio ~ `" type mpegvideo alias 
myFile`);
        auto played = mciSendString("play myFile wait");
        scope(exit) mciSendString("close myFile");
}
