Re: [NTG-context] fonts (in luatex) (again)

I don't even know what a .dfont is :-/

It's a file that packs several font files (usually the four basic ones) into one. I don't know the details of the format, but I expect that it really only contains the font file, with a few headers. Fontforge has known how to handle it for years, so it should be manageable in Mark IV. Arthur
