IIUC, the block:

#ifdef MS_WINDOWS
		if (widename != NULL)
			self->fd = _wopen(widename, flags, 0666);
		else
#endif
			self->fd = open(name, flags, 0666);
...

Would probably need to change - instead of falling back to plain open(), 
if widename is NULL you would need to use MultiByteToWideChar before 
calling _wopen().  This assumes the unicode CRT is available of course - 
if not, I guess you'd need to call the win32 api instead of _wopen. 
Alternatively, the PyArg_ParseTuple() call could possibly be changed to 
use the 'e' format string
