Do you have an example that shows the same problem with a free

In general this is a good idea, but troubleshooting without
actually having the files on a machine can be tedious. When
reporting a font that doesn’t work as expected it is best to
include the output of

    luaotfload-tool --find=<font name> --inspect


    luaotfload-tool --find="Minion Pro Bold Italic" --inspect

(This doesn’t work with files yet but that’s a todo.) otfinfo -i
is informative as well.

I’ll look into it, but not immediately. A tracker item on github
is the best reminder ;-).

Best regards,
