I’ve traced it to luatex-basics-gen.lua. The cache is compiled
with the spec “{reduce = true}” which causes values to be
analyzed and “tonumber()”ed. If I unset the reduce flag, the
values turn out correct in the PDF.
Best,
Philipp

[NTG-context] [fontloader] cached fonts have invalid tounicode values
Hi Hans,
this has been reported by Dohyun Kim [1]: the generic fontloader
(not Context) serializes some tounicode values as Lua numbers,
not strings. When re-reading the cache file the values lose all
leading zeros, so they are no longer well-formed UTF-16BE.
...
["tounicode"]={
[2329]="E001",
...
[2384]="0063006B", -- <-- correct
[2385]=00630068, -- <-- invalid
[2386]=00740074,
[2387]=00630074,
[2388]="017F0069",
...
Best regards,
Philipp
