@lhecker commented on GitHub (Nov 21, 2023):

You're using a partially proportional font that contains ligatures for "fl", which is one of the most common ligatures: https://en.wikipedia.org/wiki/Ligature_(writing)#Stylistic_ligatures
You can continue using the same font if you disable ligatures. To do so, open your settings.json file using Ctrl+Shift+, and find your "font" settings. Then add a "liga" override like so:

"font": {
    "face": "your font face",
    "features": {
        "liga": 0
    }
}

(If you already have "features" there, in particular something that starts with "ss" (stylistic set), then try removing that first.)

This will come with a slight performance cost, however (non-default font features require complex glyph shaping).

I'm using Cascadia Code, Aptos Mono, Consolas, and other fixed-width fonts. I don't believe those are supposed to have ligatures such as this. Am I incorrect?

Your fix worked, by the way. So thank you! I wonder if I should log an enhancement that the Appearance configuration should have a checkbox to allow/dis-allow ligatures.

Cascadia Code does have ligatures for things like ==>. Cascadia Mono is the one without such ligatures. Neither of the 3 fonts you mentioned however has a "fl" ligature, so I'm not sure what font it was that you used. I'm glad the setting worked for you though!

I wonder if I should log an enhancement that the Appearance configuration should have a checkbox to allow/dis-allow ligatures.

Don't worry about it! It's been requested a number of times in the past and we recently opened a PR to address this 🙂: #16104
