Reading MSDN documentation about fopen, it seems that it can handle Unicode
UTF-16 LE, but not BE.

http://msdn2.microsoft.com/en-us/library/yeby3zcb.aspx

So, I think you should just read the raw WORDs (16 bits, two bytes) from
file, and swap the byte order from your code.

1. For each WORD in file
  2. read that WORD
  3. swap low-byte and high-byte, transforming the WORD from BE to LE
  4. store this LE word (Unicode UTF-16LE wchar_t) in memory

To swap two bytes in a word, you may use the following code:

<code>

// Converts a word from Big-Endian to Little-Endian (or vice-versa)
inline WORD SwapWordEndiannes(WORD w)
{
    // Swap low and high bytes
    return MAKEWORD( HIBYTE(w), LOBYTE(w) );
}

WORD bigEndianWord = ...;
WORD littleEndianWord = SwapWordEndiannes(bigEndianWord);

</code>
