Itʼs smaller, thatʼs for sure. And it will definitely be faster.

Steven> It feels like this should either be the full table (the one in the

Welcome to the wonderful world of Unicode. The reason the table exists
is that there are codepoints that are *not* emoji, but theyʼre part of
emoji sequences, so we still need to treat them as emoji in some
situations. Why Unicode didnʼt just make them emoji I donʼt know.
