{
	std::string str;
	if (!wstr.empty())
	{
		std::wstring_convert<std::codecvt_utf8<wchar_t>> converter;
		str = converter.to_bytes(wstr);
	}
	return str;
}

std::wstring convertStringToWString(std::string wstr)
{
	std::wstring str;
	if (!wstr.empty())
	{
		std::wstring_convert<std::codecvt_utf8<wchar_t>> converter;
		str = converter.from_bytes(wstr);
	}
