Overview

macOS has its own emoji picker with a rich set of emoji keywords. It'd be great to source keywords from it as well!

Additional Info

I'd previously tried to get the macOS keywords programmatically.
https://apple.stackexchange.com/questions/406364/decoding-dat-files-in-system-library-privateframeworks-coreemoji-framework-on-bi seemed promising at first.

Unfortunately, per the question, my version of macOS Ventura 13.2 system didn't have the CharacterPicker.strings files or an equivalent that I can find. I was only able to find the text names of emojis. See attached macos-emojis.json:

plutil -convert json -o - /System/L*/Priv*/CoreE*/V*/A/R*/en.*/* > macos-emojis.json

We'll probably need somebody well-versed in macOS system settings to get this working.
