Both of these yield nil with this patch applied (and I haven't noticed
any performance regressions). But it looks like you and Robert have a
better patch so I'll leave you to it.
However, I'd like to draw your attention to the existing hard-coded
VS-16 table here:
https://git.savannah.gnu.org/cgit/emacs.git/tree/admin/unidata/emoji-zwj.awk?h=4b3de748b0b04407d2492500c77905de56de1180#n72
It feels like this should either be the full table (the one in the
patch) or it shouldn't exist at all. But again, I'm not the expert here.
