Some warning

[uikmuuyiok]

I using Win11 + TeXLive2024 + Cygwin and FedraSerifPro A/B Version4.000 to run this project return some warnings (maybe every font return follow)

D:\texlive\2024\bin\windows\otftotfm.exe: --unicoding command: warning: bad UNICODING ('germandbls' has no encoding)
D:\texlive\2024\bin\windows\otftotfm.exe: --unicoding command: warning: bad UNICODING ('dotlessj' has no encoding)

D:\texlive\2024\bin\windows\otftotfm.exe: --unicoding command: warning: bad UNICODING ('ffl' has no encoding)

Are these warnings that can be ignored?

At the end of process get message

I don't know how to deal with...

The warnings can be ignored, I think.

Not sure why the Makefile does not work for you though.
