Interesting article. Written for beginners, conversationally. Has excessive amounts of whitespace, for "readability" I guess. But at the same time, it dives quite deep, which I don't think this "style" of presentation matches up with the amount of time a more novice reader is going to devote to a single long form article.

As to the content, for all the deep dive, a simple link to https://unicode.org/reports/tr51/#Flags and what an emoji is, would have saved so much exposition. I also wish he'd touched on normalization. With the amount of time he's demanding from readers he could have mentioned this important subject. Because then he could discuss why (starting from his emoji example) a-grave (à) might or might not be reversible, depending how the character is composed.

Also wish he'd pointed to some libraries that can do such reversals.
