Woman

Most emoji stand alone. This one is infrastructure. 👩 is a base character other sequences are assembled from: attach a skin tone modifier for six variants, join it to a tool or symbol with a zero-width joiner and you get an occupation — woman plus microscope, woman plus laptop, woman plus wrench — and join two of them around a heart and you get a couple. A large share of the human emoji on your keyboard are sequences with this character somewhere inside.

That composition scheme is also where things break. A joiner sequence is only as good as the vendor's support for it, and when a platform doesn't recognise a particular combination it falls back to showing the parts. An unsupported woman farmer arrives as a woman, an invisible joiner, then a sheaf of rice. The fallback is working exactly as designed and still reads as a mistake.

Worth knowing before you put one in a form field: what looks like a single emoji here can be five or six code points. 👩 sequences routinely blow past character counts, truncate in the middle and delete one keypress at a time in text inputs that don't handle graphemes properly — which is most of them.
