 705 /*
 706    Here are the gory details. We want to follow the Windows/MS conventions,
 707    that is to have
 708
 709    In ANSI mode:
 710
 711    format specifier         results in
 712    -----------------------------------
 713    %c, %hc, %hC             char
 714    %lc, %C, %lC             wchar_t
 715
 716    In Unicode mode:
 717
 718    format specifier         results in
 719    -----------------------------------
 720    %hc, %C, %hC             char
 721    %c, %lc, %lC             wchar_t
 722
 723
 724    while on POSIX systems we have %C identical to %lc and %c always means char
 725    (in any mode) while %lc always means wchar_t,
 726
 727    So to use native functions in order to get our semantics we must do the
 728    following translations in Unicode mode (nothing to do in ANSI mode):
 729
 730    wxWidgets specifier      POSIX specifier
 731    ----------------------------------------
 732
 733    %hc, %C, %hC             %c
 734    %c                       %lc
 735
 736
 737    And, of course, the same should be done for %s as well.
