With the release of Unicode 16.0 this September, I may finally be able to use my own language’s script. But I am not sure if OSes will directly support the latest version of Unicode immediately. How long should I expect these changes to be available on my local OS?

With that being said, I would like to work on creating my own font, maybe also migrate a few corpuses from the wrong script to the original, new one, as well as work on transliteration.

All of this is impossible for a single person - but I would like to take it slowly. What would be a good place to start? Do I need to keep anything else in mind while starting on this journey?
