            Bug ID: 48444
           Summary: std::wcout locale defaults to C
           Product: libc++
           Version: 11.0
          Hardware: PC
                OS: FreeBSD
            Status: NEW
          Severity: enhancement
          Priority: P

This
> std::cout << "std::wcout's locale=" << std::wcout.getloc().name() << std::endl;
prints "C" by default, despite user's locale being en_US.UTF-8

Is the choice of "C" based on some requirement stated in standards?

As it is now, users always need to call "std::wcout.imbue(std::locale(""));" in
order to make std::wcout usable with non-ASCII characters.

It would seem that std::wcout's default of "" or same as user's locale would
have been more practical.

Do users really always need to call "std::wcout.imbue(std::locale(""));" before
std::wcout can become usable?

OS: FreeBSD
clang-10
