Eli> affects also the VS-n selectors. But since the latter setting of

Eli> (set-char-table-range composition-function-table '(#xFE00 .
#xFE0E) elt)
Eli> (set-char-table-range composition-function-table '(#xE0100 .
#xE01EF) elt))
Eli> takes care of all the VS-n selectors except VS-16, and your patch now
Eli> will take care of VS-16, it sounds like we don't need to care about
Eli> other VS-n selectors?
Eli> Or are you saying that without including VS-15, CHAR+FE0E is not
Eli> displayed using its text representation?
Not quite. If I donʼt have compose-gstring-for-graphic for VS-15, no
composition occurs for CHAR+FE0E. With my change youʼll get
composition, but itʼs still not 100% correct: CHAR+FE0E when CHAR is a
member of the emoji script will use emoji presentation, not text, but
the extra empty box will not show, so itʼs still an improvement.
Eli> Did you test the proposed change with the admin/emoji-*.txt files, to
Eli> make sure they all still display OK?
Yes. Iʼve also got a change that makes Emoji_Keycap_Sequence work, but
I think we can leave that for master.
