Add Greek support

[inferno986return]

I love this font family and use it as my daily sans-serif in Brave, particularly the new italic which is a real improvement!

Can I request Greek language support, at least the monotonic glyphs? Perhaps polytonic in the future if there's demand for it.

Open to this. To be honest, I don't anticipate starting it any time soon, but we can let this thread collect comments and upvotes and see where things go 🙂

Sounds good, I should be able to look at this once I've finished the Cyrillic support, which shouldn't be much further away.
