A minor correction: > Let's say we want to display the emoji for a brown man, “<brown man>”. There isn't a code point for that. Instead we use “<man> ZWJ <brow

A minor correction: > Let's say we want to display the emoji for a brown man, “<brown man>”. There isn't a code point for that. Instead we use “<man> ZWJ <brown>”. (with the emoji replaced, as I expect HN would strip them). That's inaccurate: skin tone modifiers are used directly after a base emoji character, without a zero-width joiner in between.
