Fonts are tricky, and as a consultant it's even trickier because of licensing models and communication between multiple parties. So I've made this checklist:
- Font family (e.g. "Times New Roman")
- Variations of said family (e.g. "bold")
- License to use those on a public website
- It has all the glyphs needed for target languages (see example)
- Hosting options:
- Externally (e.g. Google Fonts)
- Internally (e.g. same server as website or CDN)
