2 years ago This sounds more like a DOM question, e.g. given a specific character in a text run, what actual font was used to render it.
Also potentially related to https://github.com/WICG/canvas-formatted-text ?
It might be nice if the font API also exposed what fallback fonts the browser is using. So, if I need to render some sans-serif text, and it's missing some Chinese and Hindi characters shapes, Chrome knows how to fallback to other fonts for those characters. It would be great if I could query the browser for how it handles those fallbacks, so then I could emulate that behavior in JavaScript and substitute fonts in the same way for missing characters.
