std::wcout can't print out Arabic chars and some mathmatical symbols

[Falconapollo]

Recently I want to find a general solution for std::wcout so that it can print out all unicode strings. but, after poking around on google, i can't find useful. I'm stuck here, anybody can help me? _setmode(_fileno(stdout), _O_U16TEXT); won't work as expected. Here is my current code snippet:

            auto previousMode = \_setmode(\_fileno(stdout), \_O\_U16TEXT);
	std::wifstream wifs;
	wifs.imbue(std::locale(wifs.getloc(), new std::codecvt\_utf16));
	wifs.open(L"F:\\\\重要网址.txt", std::ios\_base::binary);

	std::wstring line;
	std::getline(wifs, line);
	
	wcout << line << endl;
	wifs.close();

	wcout << endl;
	cout << "∦" << endl;

	std::wofstream wofs;
	wofs.imbue(std::locale(wifs.getloc(), new std::codecvt\_utf16));
	wofs.open(L"F:\\\\iMoney.txt", std::ios\_base::binary | std::ios\_base::ate);
	wofs << line << endl;
	wofs.close();
	//it's important to restore mode to previous, otherwise std::cout will cause crash
	\_setmode(\_fileno(stdout), previousMode);

and here is some symbols to test your slution before post here: ∀, ∁, ∂, ∅, ∰, ∵, ∺, ⊙, ⋾, ⋻, ⋱, ⋭, ⋣, ⋧ Arabic: لطيفة الطقس اليوم
