Problem using TagLib::FileRef under Windows with exotic filename

Sorry about this silly question but I tried many many things to get a  
small C++ function to open an MP3 file with TagLib under Windows, and  
yet, I can't get it to work with exotic filenames (such as Japanese  

Here is basically what I did:

string utf8 = "C:\\path\\to\\audioFileWithJapaneseFilename.mp3";
int charcount = MultiByteToWideChar(CP_UTF8, 0, utf8.c_str(), -1,  
NULL, 0);
wchar_t* buf = new wchar_t[charcount];
MultiByteToWideChar(CP_UTF8, 0, utf8.c_str(), -1, buf, charcount);
TagLib::FileRef f(buf);

I generated a Visual Studio 2008 project with Cmake and the sources of  
TagLib, and I modified the main function of tagreader.cpp to put this  
code within the main function (and I removed the "for" loop). And I am  
sure my tagreader.cpp file is encoded in UTF-8.

Under Mac OS X and Linux, my problem is already solved thanks to  
QFile::encodeName, but I really can't get this small piece of code to  
work under Windows. And I accept to use almost any solution: using  
some special function of Qt, or using MultiByteToWideChar, or anything  

Thank you very much in advance.
