Identifying letter O from 0 and vice versa

posted by Jack Ward , 1723 days ago , show insights

Often I come across a situation on the web where I have to spend time deciphering whether the character is English alphabet O or the number 0 but almost always get it wrong. Due to seemingly unlimited number of fonts on the web, websites especially one involving some random alphanumeric codes often suffer from this issue.

I think, this is purposeful for captcha to deliberately put automated tools into misery; but this happens way too often with general text i.e those which are not in captcha as well.

I would like to have some kind of tool, which helps me differentiate 0 from O and vice versa on demand.
