New subject: [fontloader] cached fonts have invalid tounicode values

27 Jun 2013

      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

    (Kim’s example works with luatex-plain if you comment out the
    ``\input luaotfload.sty`` line.)
