I read the comments here first and expected the O and 0 to be indistinguishable, but for me it's prety easy to tell.

See for yourself - I flipped a 0 and an O on this image, can you tell where? https://imgur.com/a/3hcg3zH

C0H .OO

yeah. pretty easy, right?

Damn you Poe's Law

not sarcastic.

(For me it's easy but I prepared the modified image, so not blinded - hence my question that it's easy, right.)

I honestly can't. And in any case, the real test is the individual characters in isolation.

I see the O flipped to 0, but the 0 flipped to O doesn't look out of place to me.

>I see the O flipped to 0, but the 0 flipped to O doesn't look out of place to me.

real question - so how did you know there was an 0 flipped to O as well?

Not a good choice for a programming or console font, then...

A slash or dot for disambiguating zeroes would add a lot of noise visually especially in dense displays. Perhaps that's why.

I agree, a typeface for numerical use should pay attention to that! I like the typeface used in new versions of JetBrains IDEs like Pycharm. There's special attention paid to disambiguating 0 from O and also ; from : and many other details!
