Do you mean for the following code?

	QString().sprintf("%ls", otherqstring.utf16())

I didn't know that was possible until you mentioned it. I doubt many people 
are using it. Note that it's also different from the real printf's %ls, which 
expects wchar_t*, not ushort*.

Changing to QByteArray would mean assuming an encoding *if* we keep our own 
code. I'd much rather this used vasprintf and let the system deal with it. (In 
that case, wide strings would be converted using an equivalent of 
toLocal8Bit()).

This is a source of subtle bugs, so I'm going to drop the proposal. Just make 
the functions static and we'll work on a proper C++11 replacement later.
