Where are the emoji *category* icons stored on OSX? The emoji picker on OSX has a series of "category" icons, which emoji are grouped by:



Do you know where those can be found? I looked in the system icons directory, /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/, and couldn't find them there.

I then used Font Book to look at all of the symbols in the Apple Color Emoji font, and I couldn't find them there, either.

Are there other common places that Apple stores resources for apps? Do you know where these things are stored?

Thanks!
The icons are stored as PDF and TIFF files in the resources for the character palette:

/System/Library/Input Methods/CharacterPalette.app/Contents/Resources/
