 741    More Unicode complications: although both ANSI C and C++ define a number of
 742    wide character functions such as wprintf(), not all environments have them.
 743    Worse, those which do have different behaviours: under Windows, %s format
 744    specifier changes its meaning in Unicode build and expects a Unicode string
 745    while under Unix/POSIX it still means an ASCII string even for wprintf() and
 746    %ls has to be used for wide strings.
