I was under the impression that Thomas was unfamiliar with your
implementation, so I kind of waited for your authoritative answer.

Now, seeing how many users face real-world problems using console
applications they are not necessarily equipped (or even allowed) to patch,
I do see the need for a sensible default code page.

Hopefully you agree that in light of this, it does not matter whether it
was "actually buggy behavior". Nobody cares whether it was buggy or not,
when it breaks *quite* a few existing workflows.

In our case, the default code page should quite clearly be UTF-8 because
that's what `/etc/profile.d/` configures when it passes the `-U`
flag to `locale` to determine the value of the `LANG` variable.

I would really appreciate your help to get there.


P.S.: what you suggest implicitly to be the solution ("just call
`SetConsoleOutputCP()` in your console application!") seems to be fraught
with a bit of peril, see e.g.
