Thanks.  That's expected, more or less.  The conclusion is that UTF-8
can be used as a locale's codeset (good!), but sending UTF-8 text to
the console still doesn't work well (not so good).  So if people use
this knob in Windows 10, they should arrange for console input and
output to be in some codepage other than 65001 (a.k.a. UTF-8).

It's possible that using a better font for the console, such as Lucida
Console, will at least allow you to show Latin, Cyrillic, and Greek
characters in HELLO, btw.  Not sure what will happen with characters
beyond the BMP, maybe Windows 10 has improved in that part as well.
