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