Yes, that's how I implemented it. strcoll/wcscoll are using
CompareStringW, strxfrm/wcsxfrm are using LCMapStringW.
I was just asking because I wasn't sure if I had to use the
NORM_IGNOREKANATYPE and NORM_IGNOREWIDTH flags or not. But another look
into the definition of strcoll/strxfrm answered the question eventually.
