Spelling mistakes are better than nothing, but if I can obtain two copies of the document, I can diff them and fix the mistakes.

- eli 16y agoI could diff a dump of all the kerning values too.
- Groxx 16y agoI picked spelling specifically because copying / OCRing will destroy kerning values, but not (likely) spelling. And if you change words into other words, running a spell check might not clean them out either :) But yes. Diffing is always an option, and it's an ideal way to reveal steganographic data if you encode more than one thing in the same document.
