The Twitter Twemoji (12.1.3) emoji for "people holding hands" (explicitly not gender-specific) is identical to that of "man and woman holding hands". Hrm. (They do have "person", which is its own non-gendered drawing, just not a pair holding hands.)

(I believe this has been the case for a while, possibly back to around Unicode 10 when "person" was introduced, but it's somewhat surprising to see that it's *still* the case, lo these many years.)
