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