Request Greek support

[inferno986return]

Font Name (Geist Sans/Geist Mono):

• [x] Geist Sans
• [x] Geist Mono

Description of the Issue: Provide support for the Greek alphabet. The contemporary monotonic Greek alphabet should be fine for most use cases. 😊

I can see that the lowercase Greek letter Pi π and the capital Greek letter Omega Ω are already present.
