None and yet all the fonts.
Not sure what the large scale implications would be but instead of attempting to keep on top of font requests, which we all know you're going to get too many... instead, why not make an easy user experience to upload their own font files to use in a way that's safe for gitbook. Just a thought. Thanks for listening!
Font Request - Montserrat
Why do we have to go through a request process? Why not just let us use any Google font we want?
Font Request - "Noto Sans CJK TC" and "Noto Serif CJK TC"
These two font families not only are high-quality but also freely available. They are good solution for articles written in Traditional Chinese.
Font Request - IBM Plex Sans
IBM Plex Sans & Plex Mono from Google Fonts would be great and on-brand for us.
