That looks like a bitmap font specifier. Does:

	xterm -fd 'Noto Color Emoji:style=Regular'

followed by:

	echo $'\U1F3A4 \U1F352'

produce the microphone and cherry glyph (in B&W)?


No.



I get B&W emojis on 9.2_STABLE (bin pkgs from 2021Q4) with:

xterm: XTerm(366) system xterm
emacs: GNU Emacs 26.3
firefox: 95.0.1nb1

The only non-standard font-related things that I"ve done is:

$ cp /etc/fonts/conf.avail/70-no-bitmaps.conf ~/.config/fontconfig/conf.d/.

and in ~/.xinitrc:
```
# Remove 75dpi fonts
xset -fp /usr/X11R7/lib/X11/fonts/75dpi/

# Put the add-on TTF fonts before the system ones.
xset +fp /usr/pkg/share/fonts/X11/TTF/

xset fp rehash
```

Emacs 26.3 displayed hex-boxes instead of emojis, so I added this to
~/.emacs (as per https://ianyepan.github.io/posts/emacs-emojis/):
```
(when (member "Noto Emoji" (font-family-list))
  (set-fontset-font
    t 'symbol (font-spec :family "Noto Emoji") nil 'prepend))
```

Try "Noto Color Emoji" with your latest emacs.

Firefox produces this error in the F12 debugger:
```

My test file is attached.
