Hi,
another bug in LuaTeX: If LuaTeX tries to calculate the size of a CFF table where the second entry in the table is a real number, `pack_real` is called with `work_buffer+i` for a small `i`. This causes aliasing issues because `work_buffer` writes into `work_buffer` using `sprintf`. So the output from `pack_real` modifies `work_buffer` before the digits are read completely, causing LuaTeX to complain about a "invalid character".
An example to reproduce the issue:
Run the following plainTeX document with the attached version of `LOGO10.otf` (the font was created by reordering the Private table entries and has an invalid checksum, but this is ignored by LuaTeX)
hm, not sure about invalid checksum... can you try to fix it with ttx ? (be careful, change the name of the new otf ie CFFFont name etc) -- luigi
