For comparison (not trying to be argumentative!), it looks pretty good in gnome terminal on linux mint:

I only mention this because I've used these to decorate tables in my own notes in the past. It's not really worth the trouble, but I remembered being impressed with how nice these characters looked at the time.

If anyone else wants to try it, paste this into a python REPL:

    print("\u250f\u2501\u2513\n\u2503 \u2503\n\u2517\u2501\u251b")

Yeah, this is purely a issue of poor support for box drawing characters by the font.

Eg, I get:

Edit: how do I force HN to turn URLs into links? It usually does that automatically. Code-blocked for now.

Is there a way for a font to "know" at what line spacing it is being rendered?

I don't think it is controllable by the font; the only issue I can see if these lines and corners are not extended all the way to each character cell's bounding box.
