And, of course, the same should be done for %c as well.
- 4) Finally, in UTF-8 build when calling ANSI printf() function, we need to
- translate %c to %s, because not every Unicode character can be
- represented by a char.
-
wxScanf() family of functions is simpler, because we don't normalize their
variadic arguments and we only have to handle 2) above and only for widechar
