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?
If you are seeing non-empty tounicodes then most likely the font is
not processed in harf mode, the only way I set them is through a
callback that is missing from luatex.

Khaled
