Additional notes

Problem isn't reproducible with any other terminal, just Contour

[christianparpart]

Hey. Many thanks for your interest and feedback on this behavior. We're actually "just" using fontconfig for matching fonts.

If there's anything to fix on our side, I'd like to get that included in a potential christmas release (hohoho!), but for that, maybe you can provide me with the little snipped from contour.yml that shows what you've configured to show that font.

Ideally also with a link to the font file you have downloaded?

I'll be trying to look into this ASAP.

And sorry for the inconviniences.

[AlexKurisu]

Sure.
Iosevka TTC
contour.yml

Also tested with st (which also just uses fontconfig) - everything is correct, so looks like it's not fontconfig problem

@AlexKurisu thanks for the links. I'll check it out. But one thing ahead of time:

Would you mind giving it a try to set this value from true to false? Fonts that are not strictly mono-spaced (and advertised as such) will be excluded otherwise.

[AlexKurisu]

@christianparpart tried to set strict_spacing to false. Nothing changed.

[christianparpart]

Okay I can reproduce this. I'll look into it ASAP.

If I install Iosevka from ttf files then these fonts work. But setting weight to ultra light doesn't work which is a weight option that Iosevka comes with.

[christianparpart]

I think this is how it should look like instead. I'll create a PR soon, @AlexKurisu - are you also able to build from source?

[AlexKurisu]

@christianparpart yes, I can
