My understanding is that Windows switched to UTF-16 awhile ago.

http://msdn.microsoft.com/en-us/library/dd374081%28VS.85%29.aspx says
"Unicode-enabled functions in Windows use UTF-16"

http://en.wikipedia.org/wiki/UTF-16/UCS-2 says "UTF-16 is the native
internal representation of text in the Microsoft Windows
2000/XP/2003/Vista/CE..." and "Older Windows NT systems (prior to
Windows 2000) only support UCS-2."

I haven't actually run tests to see if surrogate pairs are handled
correctly in filesnames.
