CppUnit wstring support

Hi

Is there a plan to include wstring support out-of-the-box for CppUnit? If not, and in the mean 
time, what is the “correct” way to add support for wstring, (e.g. such that the following will 
compile on a strict compiler such as the one included with Xcode 5.1.1)?

(This is is an excerpt showing an additional test added to examples/simple/ExampleTestCase.cpp 
(with corresponding change in .h).)


#include <cppunit/config/SourcePrefix.h>

#include "ExampleTestCase.h"

//HERE

#include <string>


CPPUNIT_TEST_SUITE_REGISTRATION( ExampleTestCase );


…


void ExampleTestCase::exampleForWString()

{

    std::wstring ws1 = L"Hello";

    std::wstring ws2 = L"Goodbye ????????";

    CPPUNIT_ASSERT_EQUAL (ws1, ws2);

}


…


My solution was to #include “CppUnitWstringSupport.hpp” where after the line “//HERE”, this is the 
content of CppUnitWstringSupport.hpp:


#ifndef CPPUNITWSTRINGSUPPORT_H

#define CPPUNITWSTRINGSUPPORT_H


#include <iostream>       // std::cout, std::hex

#include <string>         // std::string, std::u32string

#include <locale>         // std::wstring_convert

#include <codecvt>        // std::codecvt_utf8

#include <cstdint>        // std::uint_least32_t




namespace CppUnit {

    template<>

    struct assertion_traits<std::wstring>

    {

        static bool equal(const std::wstring& x, const std::wstring& y)

        {

            return x == y;

        }



        static std::string toString(const std::wstring& ws)

        {

            std::wstring_convert<std::codecvt_utf8<wchar_t>,wchar_t> cv;

            return cv.to_bytes(ws);

        }

    };

};


#endif // CPPUNITWSTRINGSUPPORT_H
