c++ can't get "wcout" to print unicode, and leave "cout" working

can't get "wcout" to print unicode string in multiple code pages, together with leaving "cout" to work

please help me get these 3 lines to work together.

std::wcout<<"abc "<<L'\u240d'<<" defg "<<L'א'<<" hijk"<<std::endl;std::cout<<"hello world from cout! \n";std::wcout<<"hello world from wcout! \n";

output:

abc hello world from cout!

i tried:

#include <io.h> #include <fcntl.h>_setmode(_fileno(stdout), _O_U8TEXT);

problem:"wcout" failed

tried:

std::locale mylocale("");std::wcout.imbue(mylocale);

and:

SetConsoleOutputCP(1251);

and

setlocale(LC_ALL, "");

and

SetConsoleCP(CP_UTF8)

Nothing worked
