Comment(by simonmar):
There are still too many unknowns here.
* Won't `_O_U8TEXT` do newline mangling too? The IO library already does
that, so we could have a problem.
* the original report said that piping the output to a file worked fine.
So presumably we need to do this only when the file descriptor is attached
to a console?
And I still don't understand exactly what this `_setmode` is a workaround
''for''. Something apparently goes wrong when you try to output Unicode
to the console, but at what layer does the problem occur? (GHC.IO, msvcrt,
Win32, kernel)
I don't like to be obstructive when there's an apparent fix for a problem,
but I've seen many cases where a "fix" has introduced new problems, so I
want to make sure the cure is not worse than the disease :)
