 699    Here are the gory details. We want to follow the Windows/MS conventions,
 700    that is to have
 701
 702    In ANSI mode:
 703
 704    format specifier         results in
 705    -----------------------------------
 706    %c, %hc, %hC             char
 707    %lc, %C, %lC             wchar_t
 708
 709    In Unicode mode:
 710
 711    format specifier         results in
 712    -----------------------------------
 713    %hc, %C, %hC             char
 714    %c, %lc, %lC             wchar_t
 715
 716
 717    while on POSIX systems we have %C identical to %lc and %c always means char
 718    (in any mode) while %lc always means wchar_t,
 719
 720    So to use native functions in order to get our semantics we must do the
 721    following translations in Unicode mode (nothing to do in ANSI mode):
 722
 723    wxWidgets specifier      POSIX specifier
 724    ----------------------------------------
 725
 726    %hc, %C, %hC             %c
 727    %c                       %lc
 728
 729
 730    And, of course, the same should be done for %s as well.
