Ah, I see.

I don't know, but I would bet that the sum of all corner cases and exceptions in the world would make it pretty hard to confidently eliminate any "obvious" characters.

From a technical standpoint, unicode emojis are probably safe to exclude, but on the other hand, some scripts like Chinese characters are fundamentally pictograms, which is semantically not so different than an emoji.

Maybe after centuries of evolution we will end up with a legit universal language based on emojis, and people named with it.

Chinese characters are nothing like emoji. They are more akin to syllables. There is no semantic similarity to emoji at all, even if they were originally derived from pictorial representations.

And they belong to the {Alphabetic} Unicode class.

I'm mostly curious if Unicode character classes have already done all the hard work.
