<iostream>: unicode(0x2013) brings wcout to set badbit

when I want to print 0x2013 to wcout, wcout set badbit.

Command-line test case

C:\Temp>type repro.cpp
#include <iostream>
#include <io.h>
#include <fcntl.h>

int main() 
{
   wchar_t cc = 0x2013;
   //_setmode(_fileno(stdout),_O_U16TEXT); (1)
   std::wcout << cc << std::endl;
   std::wcout << L"wcout set badbit\n";
   return 0;
}

but when I uncomment line (1) it works.
is this deliberate behavior?

Visual Studio 2019 Version 16.5.5

Start with the repro.cpp command-line case and compare std::wcout behavior for wchar_t 0x2013 with and without _setmode(_fileno(stdout), _O_U16TEXT). Trace the relevant Windows console and stream-state handling, then establish whether the badbit result is intentional; done means a confirmed expected behavior or a focused regression test and fix.
