>Intermediate versions can't add any new characters, but can add sequences
and properties, including "emojification" of existing characters.
E.g. E4.0 didn't reference any characters from U10.0. It did recognize
*sequences* of existing U9.0 characters.
E5.0 did have the emoji properties of some 10.0 characters a bit ahead of
time, but only after they were completely locked down.
