It's a few versions behind and I don't enough have enough time and patience to fix the script that generates the files.
This repository contains Twemoji as compiled COLR/CPAL font. I use twemoji-colr from mozilla to create the font. For now I'm going to place only the compiled files into this repository. Maybe I'll change the structure some day so the font files will be created and published automatically. But there is a lot of work to do. Take a look at the issues for more information.
The latest version (15.0.3) uses a fork of twemoji because the original repository seems to be dead. For more information see https://github.com/jdecked/twemoji
