Interestingly, while it uses diffusion, it generates incorrect information, and it doesn't fix it when later in the text it realizes that it is incorrect:

  > The snail you’re likely thinking of has a different code point:
  > The correct code point for the snail emoji is U+1F40C? No—U+1F40C is SEAHORSE. The snail’s true code point is U+1F40C? Wait, this is still confusing.

  > Given the confusion, the safest answer is: the Unicode Standard defines U+1F40C as “SEAHORSE”. If your device shows a snail, it’s a rendering quirk, not a change in the underlying code point.
