- 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):
-
- wxWidgets specifier POSIX specifier
- ----------------------------------------
-
- %hc, %C, %hC %c
- %c %lc
-
-
- And, of course, the same should be done for %s as well.
