“WHAT IS THE DEAL WITH THE HANDSHAKE EMOJI?” It’s a good question and worth asking in all caps. Of our many body part emoji that have skintone, Handshake (????) appears to be left by the wayside. After inquiring with the Unicode Technical Committee (UTC) it was clear there was a desire to address it and it was possible to fix but no one had yet proposed an appropriate solution to make it happen.

This is a well written, entertaining look at the process of moving from a need (handshakes did not represent multiple skin tones) to a reality in the emoji universe.
