Certain characters are not monospace

Problem

Certain characters used in terminal UIs are not monospace. Here is a screenshot with Argon for the following text:

textln!["╭ In progress ─────────────────────────────────────────────╮"],
textln!["│                                                          │"],
textln!["╰──────────────────────────────────────────────────────────╯"],

To confirm its an issue with Argon and not VSCode, I tried it with the Hack font, and that looks fine:

Fonts observed on

I only tried it on Argon and Neon, and it occurs on both.

This is because of the ligature.

That's because box drawing characters are not supported. There's a temporary partial fix in https://github.com/githubnext/monaspace/issues/43#issuecomment-1806688727

Box drawing glyphs are added in 1.2!

Enjoy all the boxes! ✨
