They say you should never read the comments on YouTube... but I've never been much good at taking advice, so let's read the comments. 🤠 Turns out over the course of my history of text encodings, I got some stuff wrong (oops), there's a bunch of cool things I didn't know about, and there's some stuff I *did* know about but completely forgot to mention. Huge thanks to everybody who took the time to watch and reply - I really appreciate it!
