I didn't disagree to your proposal. But actually m$ itself does not
use utf-16 in all its products. IIRC win9x/me use ucs-2 and vi$ta
should utf-16. winxp sits in between, it used ucs-2 in the beginning
and some patches were issued to make some component (eg chinese ime)
utf-16 awared.
I think that ucs-2 is still more popular than utf-16 in that the
number of program of that support ucs-2 but not utf-16 is greater than
that support utf-16. Anyway just a wild guess, who cares for utf-16.
