rapidjson 中文乱码的问题

[tony2278]

rapidjson::Document doc_config;
int ret = GetDocumentFromJsonFile(path, doc_config);
const rapidjson::Value& myValue = doc_config["myKey"];
std::string data = testing["mySubkey"].GetString(); //here

//data 如果存在中文就会乱码，应该怎样转换处理呢？谢谢!

json是utf8需要转换成unicode或者ansi使用这个转换：

	wstring StringHelper::UTF8ToUnicode( const string & s)
	{
		wstring result;

		int n = MultiByteToWideChar( CP_UTF8, 0, s.c_str(), -1, NULL, 0 );
		wchar_t * buffer = new wchar_t[n];

		::MultiByteToWideChar( CP_UTF8, 0, s.c_str(), -1, buffer, n );

		result = buffer;
		delete[] buffer;

		return result;
	}


	std::string WChar2Ansi(LPCWSTR pwszSrc)
	{
		int nLen = 0;
		nLen = WideCharToMultiByte(CP_ACP, 0, pwszSrc, -1, NULL, 0, NULL, NULL);
		if (nLen<= 0) 
			return std::string("");

		char* pszDst = new char[nLen];
		if (NULL == pszDst)
			return std::string("");

		WideCharToMultiByte(CP_ACP, 0, pwszSrc, -1, pszDst, nLen, NULL, NULL);
		pszDst[nLen -1] = 0;
		std::string strTemp(pszDst);
		delete [] pszDst;

		return strTemp;
	}
