I am trying to do this - converting from wstring works incorrectly!
I need add to json array of objects wstring values,
and then convert to plain wchar_t string!

But all I try - didnt work! This is screenshot!

auto jsonProducts = json::array();
while (...) {
  std::wstring productRID_w (ValByName(GoodsQ));
  std::wstring productName_w (ValByName2(GoodsQ));
  // convert to json
  json product = {
	{"productRID", productRID },
	{"productName", productName}
  };
jsonProducts.push_back(product);
}
std::string jStr = jsonProducts.dump();
std::wstring widestr = std::wstring(jStr.begin(), jStr.end());
wchar_t* tempWide = const_cast<wchar_t*>(widestr.c_str());
return tempWide;

So, the wstring L"test" after adding to jon object becomes "Р\xfҐP\a"

What the hell, man?
How to fix it?
Or suggest a normal C ++ library that can work correctly with wstring.
Be so kind....
