The Unicode Consortium has a public list of emoji proposal and what stage of the process they’re in. Here are some of my favorites that didn’t make the cut:

• Cutlet - I support this proposal
• Drop of pee - I struggle to see a scenario where this would be needed
• Gender Gap Fill - a worthy cause, although I struggle to see how this would be represented as an emoji
• Healthy Poo - the current poo is has no medical indicators, I agree
• Intestines - OK, but why?
• Possibly Bird - I guess this is possibly a bird and possibly a rabbit
• Object related - I guess someone wanted to start adding UML symbols to emojis?
• Stegosaurus - I completely agree. The current dinosaur selection is incomplete. It’s a shame that it expired because it had a good chance of being approved because triceratops was accepted.
• Viking / Horned Helmet
• Winking with thermometer - 🤔

Also fun are the overly specific emoji requests, such as “Pandeiro” because “Drum” just doesn’t convey the same thing.

Here is the full list.

I found this because I was looking for instructions on how to submit a proposal for a new emoji. Unfortunately, they only accept proposals till 31 Aug so I’ll have to wait till next year.
