i fixed something in the next beta for these type 1 fonts (with slightly weird encodings)
I'm getting some weird errors with the most recent versions of ConTeXt too. Currently I can't send you a sample to reproduce the problem but I can only describe what happens with a big XML file of mine under these 3 conditions: 1 - latest beta (2017-06-29 9:32), with some OTF fonts (Garamond Premier Pro, Myriad Pro, Quivira): the program ends with this error luatex warning > nodes: attempt to copy free glyph (f) node 67776, ignored ! error: (linebreak): invalid list tail, probably missing glue 2 - latest beta (2017-06-29 9:32), without OTF fonts: the program works 3 - ConTeXt 2016.05.17 from Debian repositories, with the fonts of case 1: the program works Sorry for such an imprecise feedback, Best greetings, Massi
