How are some of the jgs9 glyphs perfectly smooth? e.g the infinity symbol

In Chrome Dev Tools, we can inspect those glyphs by scrolling to the bottom of the Computed styles tab. The sibling commenter is correct: they don't exist in the font yet, and are falling back to the browser default: https://i.imgur.com/nq8Qdct.png

I assume that those are placeholders for characters not yet present in the font?
