Bug report

In both Jupyter Notebook and Terminal, I cannot display emojis using the Apple Color Emoji font.

If I attempt to setfontname='Apple Color Emoji' matplotlib won't find the font, and falls back to the default font DejaVu Sans, which renders the image below.

If I try to load the font usingfont_manager.FontProperties, it throws an error:RuntimeError: In FT2Font: Could not set the fontsize.

Code for reproduction
