I know this :-( I strongly prefer to use straigt TCHAR
programming, without any conversions. This is why I
started to work with it in the first place.

There is no such issue for Windows compilers. Can we
have requirement of 2-byte Unicode characters compiler
for the tests?
In the worst case people, who do not have such
compiler will be able to run tests in ANSII mode only.

Do you mean using -fwritable-strings parameter or
performing explicit conversion? Can we hide explicit
conversion in the _T/_TEXT macros?

IMHO this is much bigger mess than with compilers.

Here I don't agree with you. Programming with TCHAR is
*exactly* the same as programming with WCHAR, but with
different names. You think once - in WCHAR terms and
get as a bonus ANSII version!

In fact, code became clearner after I removed "if
(has_unicode()) " blocks, A<->W conversions, letters
"A", "W" from API names. I feel that in this case I
don't need to "think twice" - once in terms of ANSII,
the second time - in terms of Unicode.
I moved test completely to using TCHAR (attached).
Compare it with the version which uses explicit
"W"/"A" calls.
