For -m32 (DIGITAL_MARS_STDIO) it seems to come down to this (with `chcp 65001`
in the console):

----
import std.stdio;

void main()
{
    FILE* fps = core.stdc.stdio.stdin;
    FLOCK(fps);
    scope(exit) FUNLOCK(fps);

    auto fp = cast(_iobuf*)fps;
    assert(!(__fhnd_info[fp._file] & FHND_WCHAR)); /* passes; no wide
characters */
    assert(!(fp._flag & _IOTRAN)); /* passes; no translated mode */

    int c = FGETC(fp);
    assert(c != -1); /* passes with 'a'; fails with 'ä' */
}
----

That is, Digital Mars's FGETC (_fgetc_nlock) returns -1 for non-ASCII
characters.

The issue does not manifest with a pipe: `echo ä | test` works.

The same happens with -m64, and with a simple C++ program (just `printf("%d\n",
fgetc(stdin));`). So apparently `chcp 65001` is not enough to make UTF-8 input
work from the console. I'm not much of a Windows programmer, though, so I have
no idea what's missing.

It seems to be a problem with input from a TTY. Normal stdin is a TTY, but when a pipe is used it's not. According to _isatty [1], stdin is also not a TTY when I run things in the bash from Git for Windows. And indeed: no UTF-8 problems there.
