Here are the gory details. We want to follow the Windows/MS conventions,

that is to have
|
|
|
|
In ANSI mode:
|
|
|
|
format specifier results in
|
|
-----------------------------------
|
|
%c, %hc, %hC char
|
|
%lc, %C, %lC wchar_t
|
|
|
|
In Unicode mode:

|
|
|
format specifier results in
|
|
-----------------------------------
|
|
%hc, %C, %hC char
|
|
%c, %lc, %lC wchar_t
|
|
|
|
|
|
while on POSIX systems we have %C identical to %lc and %c always means char
|
|
(in any mode) while %lc always means wchar_t,
|
|
|
|
So to use native functions in order to get our semantics we must do the
|
|
following translations in Unicode mode (nothing to do in ANSI mode):
|
|
|
|
wxWindows specifier POSIX specifier
|
|
----------------------------------------
|
|
|
|
%hc, %C, %hC %c
|
|
%c %lc
|
|
|

And, of course, the same should be done for %s as well.
