Thanks Igor ... interesting.

If you let me make a comment about your last sentence:

"My program is UNICODE only."

I think we should not use "UNICODE" when we talk about a character set
(must be "UCS-2" in your case).

UNICODE can be implemented by different character encodings, it can be
UTF-7, UTF-8, UTF-16, UCS-2, UCS-4 ...

I known the Windows people think UNICODE = UCS-2 / UTF-16 but that's
a shortcut that confuses people that are new to I18N ;-)
