I found win32file.CreateFileW (documented to deal with 'unicode'), and that did return a handle for me.  What puzzles me is that both functions take a PyUNICODE filename, so I just assumed that CreateFile would deal with the unicode pathname I was giving it.  So, my question is, should I just use win32file.CreateFileW instead of win32file.CreateFile, and is it safe to use for all file handles, including those that do not have wide characters?

I need to get the pyHANDLE to call win32file.DeviceIoControl (to set reparse data) and win32file.SetFileShortName, but if there's an easier way to programmatically set the 8.3 name on a file, please let me know.
