Here's a list of sans-serif fonts I've found that have proper capital "i":

Dejavu-sans-mono (zero clearly different)

Victor-mono (zero clearly different)

Noto-mono (zero clearly different)

Chivo (O and zero different width)

Comme (O and zero different width)

Darker-grotesque (O and zero different width)

Didact-gothic (O and zero different width)

Droid-sans (O and zero different width)

Droid-sans-mono (O and zero different width)

Metrophobic (O and zero different width)

Monda (O and zero different width)

Nobile (O and zero different height)

Noto-sans (O and zero different width)

Sen (O and zero different width)

Luciole (O and zero slightly different width)

IBM Plex (O and zero slightly different width)

Tiresias-infofont (O and zero indistinguishable)

Clear Sans (O and zero indistinguishable)

When I originally posted this list, I provided a link to every one of these fonts. Hacker News "shadow-banned" it without simply telling me that it was flagged, so I spent the time rounding up all the links and creating the list for nothing.

Why do more people not call out Hacker News for its disgraceful treatment of users and deliberate wasting their time? There's no excuse for it. Look at the way they allow you to type out a lengthy question or comment and THEN say, "OH NO, you're posting too fast. Piss off." Instead of simply DISABLING THE REPLY BUTTON.

One thing I don't like about Plex aesthetically is that the italic faces have right-facing serifs on the bottom of most letters for some reason. It's needlessly inconsistent.
