With harftex or an older luatex I get:

1 beginbfchar <0052> <0031> endbfchar

By older luatex I assume luatex with non-harf mode?

What's going on here?

The Lua code for harf mode uses a new callback in HarfTeX to set the glyphs tounicode values, because the existing mechanisms in luatex are too slow for the way I do it. I set tounicode based on shaping output, so need to be done incrementally after loading the font, while luaotfload does it by analyzing the fonts cmap and GSUB tables and can set them at once while loading the font.

hm. The interesting thing is that it works with luatex 1.11 if I load harf-luaotfload in the document, it only fails if I load it in \everyjob through a setting in a local lualatex.ini I used to build the format. Why is this? -- Ulrike Fischer https://www.troubleshooting-tex.de/
