Ok, so based on emoji-data.txt, my awk script produces the attached
.el file. It excludes U+2XXX and U+3XXX, plus U+A9 and U+AE and
anything ASCII. Note that there are duplicates in there, since some
codepoints have multiple Emoji-type properties. Of course, we could
just decide a bunch of ranges from Block.txt that we want to treat as
emoji, and hardcode that.
