Custom font upload not working

Description

When trying to install this font it wouldn't complete and instead we are seeing a browser console error.

Step-by-step reproduction instructions

1. Go to Appearance > Editor
2. Styles > Fonts
3. Try uploading this font:

AaDaoShuRi-LangManHeiTi-2.ttf.zip

Screenshots, screen recording, code snippet

The console renders:

Uncaught (in promise) SyntaxError: Invalid font data in ArrayBuffer

Th workaround is to convert it to a .woff2. I've used https://transfonter.org/
