According to the "Can I Unicode‽" web page, as of today, the #Chrome navigator is still "stuck" in Unicode 15.1, while the latest version of #Unicode is 17.0!

The fact that the #Electron framework is based on #Chromium probably explains why it is still lagging behind too...
Supporting Unicode 16.0 would allow me to produce a final stable version of my Unicopedia Plus app, before I can start working on a version for Unicode 17.0.
