This looks good to me, thank you!

Note that I don't have write access to the github org anymore, meaning I can't merge this nor cut a release myself.

Thank you for your review. I got it. I'll wait for some maintainer's action.

Looks like the only maintainer (with >1 commit) since 2020 is @mislav, who does not maintain this repo anymore. https://github.com/github/gemoji/graphs/contributors?from=25%2F10%2F2020&to=16%2F02%2F2025

It would probably make sense for someone to maintain a community fork of this repo.

The pull request #303 in the github/gemoji repository has no failing checks and appears to be up to task.

I believe there is a mistake will all the unicode 16.0 emojis added to emoji.json. The iOS version was not updated, staying at 16.4, while in practice the support for unicode 16.0 emojis was only added in iOS 18.4.

Unicode v17 was also released recently, and it does have a few new emojis.
