///////////////////////////////////////////////////////////////////////////////
// Name: tests/formatconverter/formatconverter.cpp
// Purpose: Test wxFormatConverter
// Author: Mike Wetherell
// RCS-ID: $Id$
// Copyright: (c) 2004 Mike Wetherell
// Licence: wxWidgets licence
///////////////////////////////////////////////////////////////////////////////
//
// 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"));
