I guessed that it would become the USSR flag (US -> SU), but apparently Unicode doesn't define that one! I wonder why. That would have been humorous.
It would have been difficult to get the CN delegation to sign off on a list that contained TW, although there are probably others.

This misses the real problem with flag emoji in that they are composed of codepoints that can be in any order. With other emoji you get a base codepoint with potential combining characters. Using a table of combining character ranges you can skip over them and isolate the logical glyph sequences. You don't need surrounding context to parse them out like flags need.
If such re-purposing continues, it might be easier to go straight to utf-32 for some use cases.
This is a cool article about Unicode encoding however I still feel like it should be possible to reverse strings with Flag emojis. I don't see why computers can't handle multi rune symbols in the same way that they handle multi byte runes. We could combine all the runes that should be a single symbol and make sure that we're maintaining the ordering of those runes in the reversed string. Of course that means that nai…
I actually don't know how/why Python is apparently using code points, since they are variable length. That seems like a compromise between using code units and using grapheme clusters that gets you the worst of both worlds.
Edit: Maybe it uses UTF-32 under the hood when it's doing array operations on code points?
did they think all those skintone emojis are individual codepoints?
So, in terms of acing interviews, increasingly one of the best answers to the question "Write some code that reverses a string" is that in a world of unicode, "reversing a string" is no longer possible or meaningful. You'll probably be told "oh, assume US ASCII" or something, but in the meantime, if you can back that up when they dig into it, you'll look really smart.
Reversing a string is still meaningful. Take a step back outside the implementation and imagine handing a Unicode string to a human. They could without any knowledge look at the characters they see and produce the correct string reversal. There is a solution to this which is to compute the list of grapheme clusters, and reverse that. https://unicode.org/reports/tr29/
Maybe I'm missing some prerequisite knowledge here, but why would I assume `flag="us"` is an emoji? Looking at that first block of code, there is no reason for me to think "us" is a single character. Edit: Turns out my browser wasn't rendering the flags.
