I added DejaVu Sans Mono per the above and to my surprise I see this:

  $ cat alfa.txt
  =EF=BF=BD

So it looks like Deja Vu has a 0xfffd char.  However, GetGlyphIndicesW
claims otherwise:

  static const wchar_t replacement_char[3] =3D
    {
      0xfffd, /* REPLACEMENT CHARACTER */
      0x25a1, /* WHITE SQUARE */
      0x2592  /* MEDIUM SHADE */
    };
  WORD gi[3] =3D { 0, 0, 0 };
  [...]
  GetGlyphIndicesW (cdc, replacement_char, 3, gi, GGI_MARK_NONEXISTING_GLYP=
HS);
  printf ("gi =3D %u %u %u\n", gi[0], gi[1], gi[2]);

This prints:

  gi =3D 65535 401 372

That means, the notdef glyph for DejaVu looks like 0xfffd, but isn't,
right?
