TYPO3 Core

There is the icons repository https://github.com/TYPO3/TYPO3.Icons with the corresponding website https://typo3.github.io/TYPO3.Icons/index.html for TYPO3 icons.

I think it would be a good thing to create icons like we did for accessibility (https://typo3.github.io/TYPO3.Icons/icons/actions/actions-accessibility.html) but I do not know where the icon fits best (should it be in "Apps" like the page icons, or in "Content", as there also might be a specific content type.)

If I am not understanding it wrong, here we're talking about adding icons on the TYPO3 backend to represent those "languages".

The problem is that.. TYPO3 uses flags as language icons so... which flag should represent for example the "sign language" ?

TYPO3 12 and 13 have a series of "non-country" "generic" flag icons to cover such cases (I guess that's the intent ):

white, blue, indigo, purple, pink, red, orange, green, teal, cyan, rainbow
