Here it is! The thrilling, nearly 2,000 word conclusion to my nostr:npub196qp059ct6svn3zjnkayllh6f552sehejrthc24e20wnt78ngsnsjm96ja project log, “A Book for Every Language”. In which we examine the vagaries of Unicode character properties, deep dive into the internals of the Open Book's language software (called Babel), and pull a rabbit out of a hat by adding proportional-width typography to the Open Book without sacrificing 100% coverage of all the world's languages. Also jokes. (I do not promise that they are good jokes.) https://hackaday.io/project/168761-the-open-book/log/222182-a-book-for-every-language-part-ii-plus-proportional-width-fonts

nostr:npub10ae605fgpw08r8d2u7u65wu82n5n02gzv4wef797z5dk7g3w8smq7xnlyc okay I sincerely cannot thank you enough: this was the issue. It's funny because the checkbox even says "recommended" in parentheses. But unchecking that box, they were able to read the gerbers immediately.

You have saved my manufacturing run. 🙏🏽
