Hi Frank,
Sorry to be in disagreement on a couple of points.

What is not true?

Yes it does. That is, the wchar_t encoding CAN change at run time if you
call setlocale(LC_CTYPE, ...)
I know this is not current behavour (fortunately), but it does happen with
some libc. And regarding the standard, this IS allowed behaviour.

In this particular example, yes, wchar_t encoding never changes (and stays
16-bit UCS-2).
But there are other compilers and other environments in the world.

This I agree with. Particularly the latter...

Here I am in agreement!
About the rest, this is factually correct. I am in disagreement with the
ideas, but I already exposed mine, so no need to repeat it.
