There is a whole bunch of weird stuff in windows, this is just another instance.

If what you want to do is read/write FLAC files with windows UCS-16 filenames,
one option is to use libsndfile:

    http://www.mega-nerd.com/libsndfile/

which with version 1.0.21 has added this function:

    /* The function sf_wchar_open() is Windows Only!
    ** Open a file passing in a Windows Unicode filename. Otherwise, this is
    ** the same as sf_open().
    **
    ** In order for this to work, you need to do the following:
    **
    **		#include <windows.h>
    **		#define ENABLE_SNDFILE_WINDOWS_PROTOTYPES 1
    **		#including <sndfile.h>
    */
    #if ENABLE_SNDFILE_WINDOWS_PROTOTYPES
    SNDFILE* sf_wchar_open (LPCWSTR wpath, int mode, SF_INFO *sfinfo) ;
    #endif

There is a windows binary installer in the main web page (one for each of
32 and 64 bit windows).

The only downside to this is that libsndfile does not expose the all of
the features of the FLAC API to the user.
