Noto Color Emoji causes a crash of the X program attempting to display

I was browsing the web when my WM suddenly crashed due to its attempt to render an emoji in the title bar. Upon further investigation, it appears to me that it was not my WM at fault, but rather Noto Color Emoji crashes any X program that attempts to render it.

NOTE: I haven't tested Noto Emoji, but it may have the same issue

Steps to reproduce:
1. Open a text editor (I use emacs) and enter a unicode character with the code 1F5BC (in emacs "C-x 8 RET 1f5bc RET"). It should display as a box.
2. Change the font of the text editor to Noto Color Emoji.

Using these steps, I have successfully crashed emacs under dwm and openbox, as well as dwm and openbox themselves by telling them to render the emoji in the title bar.

Solutions:
- Uninstall Noto Color Emoji.
- Install another font with emoji support (e.g. EmojiOne Color) and set that font to be of higher priority in fallback (in dwm you do this by adding it to the list of fonts in config.h).

Some more information about your card, driver and an xorg log with a crash in it would be useful...

Not an Arch discussion, moving to NC...

Sure.

Graphics Card: Intel Corporation HD Graphics 515 (rev 07)
Driver: i915

Xorg log: https://pastebin.com/B6Thzq4q

The log doesn't have a crash because it doesn't crash X11, it just crashes the program attempting to display it. I'll redo one of the crashes I had with dwm and drop the log here soon.
