O looks like 0 This is the worst offender. rather simliar to D and Q
l, I, 1 - at least these aren't too bad
B and 8 are pretty close
S and 5 are fairly close
Z and 2 are pretty close
' and ’ and ′ nearly identical
As a new guy someone told me to look up files for project "Eff two oh" F20 or F2O? I got no results. A lot of our projects include the generation like 1.0 2.0 1.5, etc. but that's typically spoken as one oh, two oh, one point five, etc. But some projects do have an O "oh" in them.
As a general opinion, I hate the ArtifaktElement font. It's too thin and doesn't anti-alias well.
