Why doesn't this work?

Ask Microsoft; they handle ANSI in Win 10. Apparently they don't want you to use ANSI for STDERR.
I dunno! Both of these work.

Code:
    fwprintf(stderr, L"\x01b[31;1mfoo\x01b[0m\n");
    WriteConsoleW(GetStdHandle(STD_ERROR_HANDLE), L"\x01b[31;1mfoo\x01b[0m\n", 15, NULL, NULL);
