More Unicode complications: although both ANSI C and C++ define a number of

Worse, those which do have different behaviours: under Windows, %s format
specifier changes its meaning in Unicode build and expects a Unicode string
while under Unix/POSIX it still means an ASCII string even for wprintf() and
%ls has to be used for wide strings.
We choose to always emulate Windows behaviour as more useful for us so even
