One issue this has thrown up is that the hypothetical 'emoji' script
completely subsumes U+1F000..U+1F02F (mahjong-tile) and
U+1F030..U+1F09F (domino-tile), so those scripts would no longer
exist.

Your concern here is what Emacs should do when one of the characters in this
range is followed by U+FE0E or U+FE0F?
