I see the issues with people mis-interpreting zero and “Oh” as a developer fault. There are plenty of letters, numbers and symbols that are not easy to confuse with each other. When generating license codes, simply do not use “S”, “5”, “0”, “O”, “1”, “l”, “i”, “I”. Not sure why a person would need OCR to grab a code from a web page, unless developer made the terrible choice to disallow copying the code as text. So this may also be a user fault. I’m hoping someone writes comments that actually evaluate the software, instead of people like me who ramble on about other things…. :)
