// Notes:
//
// The conversions wxFormatConverter currently does are as follows:
//
//    %s, %lS   ->  %ls
//    %S, %hS   ->  %s
//    %c, %lC   ->  %lc
//    %C, %hC   ->  %c
//
// %hs and %hc stay the same.
//
// %S and %C aren't actually in the ISO C or C++ standards, but they can be
// avoided when writing portable code.
//
// Nor are %hs or %hc in the standards, which means wxWidgets currently doesn't
// have a specifier for 'char' types that is ok for all builds and platforms.
//
// The effect of using %hs/%hc is undefined, though RTLs are quite likely
// to just ignore the 'h', so maybe it works as required even though it's
// not legal.
//
// I've put in some checks, such as this which will flag up any platforms
// where this is not the case:
//
//  CPPUNIT_ASSERT(wxString::Format(_T("%hs"), "test") == _T("test"));
//

// For compilers that support precompilation, includes "wx/wx.h".
