> This isn’t a claim that major LLMs do all (or any) of these tricks. That said, I started working on this because I accidentally discovered an instance of text fingerprinting while debugging a byte-sensitive bug. That’s when I realized: it’s time to say goodbye to (at least these kinds of) fingerprints for good.

Are there any examples of this being used?

Just try it :) I’ve definitely come across random variation selectors now and then. Otherwise, the most common case is typography: like em-dashes instead of hyphens, curly apostrophes, etc. But if you're feeding LLM output into a search tool, these subtle differences might not be helping you!
