Error: unichr() arg not in range

[b-g]

Hi there!

I'm having trouble to generate fonts with complex ligatures like 🏳️‍🌈1F3F3-FE0F-200D-1F308 or 👩‍⚕️1F469-200D-2695-FE0F. Is there a special file convention I'm not aware of?

It works out of the box for simple ones like 🏝1F3DD or 🎣1F3A3, yay!!

Here is also a self containing folder with my issue in an isolated way: OpenMoji-Colorfont-POC.zip

Sorry to bother again!

Narrow Python... what?!?! I had no idea this was a thing or even an option. Details: https://stackoverflow.com/questions/25111521/how-to-install-python-on-mac-with-wide-build

I would have written this in Python3 instead of Python2 if FontForge supported Python3, but it doesn't. Easiest option is to run this within Docker, but maybe I just say that because I deal with an inordinate amount of Docker nowadays.

@eosrei Wow this is really esoteric! :) Many thanks for clarification!

Never used docker ... but skimmed over some tutorials on the weekend. Seems doable for me or at least worth a try. Especially as getting the "wide-build" to run on 20 diverse students computer would be a nightmare (we have an upcoming OpenMoji workshop).

Could you give me some guidance e.g. FROM which image should I based everything (there a plenty of Python2 and host OS choices)? 🙏

Another option which may be easier to use VirtualBox with a regular Ubuntu install. YMMV I guess.

Use the Docker https://hub.docker.com/_/ubuntu/ image. Most recent LTS is 18.04.
