Hi all, LuaTeX stops with an error when reading version 0 OS/2 table, and this is is because it unconditionally reads ulCodePageRange1 and ulCodePageRange2 fields that were not defined in version 0. Such fonts can be found here [1] (from the question [2]). I’m attaching a patch that makes this conditional, it also fixed reading version 2 specific fields that would be skipped for tables with versions greater than 2. It does not look like these fields are used anywhere, so another fix is to only read the fields LuaTeX actually needs.
