I don't think I understand the problem.  The first 2 codepoints are in
admin/unidata/emoji-sequences.txt, and the gender thingy is what
determines if its "man" or "woman".  VS-16 is a no-op, and I'm not
even sure you should produce it in these sequences.  It is only needed
when the original character is not an emoji.
