I rendered 1,418 confusables over 230 fonts. Most aren't confusable to the eye

Maybe not at super large font sizes. But even lowercase i and l are easy enough to confuse at a glance mid-word in most sans-serif fonts, not to mention uppercase I and lowercase l. You don’t even need “confusable” glyphs to create a domain name that will stand up to a casual visual confirmation from a busy user in a phishing context.

I used to read"Weird Al" as "AI" even before the LLM craze.

This is really cool. I loved the technical breakdown and side by side comparisons. Surprised to hear that Microsoft and MacOS default fonts didn't score so well!
