 708 /*
 709    Here are the gory details. We want to follow the Windows/MS conventions,
 710    that is to have
 711
 712    In ANSI mode:
 713
 714    format specifier         results in
 715    -----------------------------------
 716    %c, %hc, %hC             char
 717    %lc, %C, %lC             wchar_t
 718
 719    In Unicode mode:
 720
 721    format specifier         results in
 722    -----------------------------------
 723    %hc, %C, %hC             char
 724    %c, %lc, %lC             wchar_t
 725
 726
 727    while on POSIX systems we have %C identical to %lc and %c always means char
 728    (in any mode) while %lc always means wchar_t,
 729
 730    So to use native functions in order to get our semantics we must do the
 731    following translations in Unicode mode (nothing to do in ANSI mode):
 732
 733    wxWidgets specifier      POSIX specifier
 734    ----------------------------------------
 735
 736    %hc, %C, %hC             %c
 737    %c                       %lc
 738
 739
 740    And, of course, the same should be done for %s as well.
