ECHOERR and color escape sequences

[vefatica]

Why doesn't this work?

This works.

Do you have a color set for stderr output?

Ask Microsoft; they handle ANSI in Win 10. Apparently they don't want you to use ANSI for STDERR.

And your second example is not outputting to STDERR, it's writing to STDOUT and redirecting that to STDERR.

Normally, yes. In my test, no.

I dunno! Both of these work.

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