I use TeXShop (v3.11) to run XeTeX on a Mac Mini. A large book project containing Chinese suddenly failed to compile with the message
** WARNING ** Unable to read OpenType/TrueType Unicode cmap table. ** WARNING ** Failed to load ToUnicode CMap for font "STKaiti" ** ERROR ** Invalid glyph index (gid 13383) Output file removed. Error 256 (driver return code) generating output; file chitest.pdf may not be valid. Just before this problem appeared, I upgraded the OS to Mac OSX 10.8, Mountain Lion. (The upgrade includes several new Chinese fonts, which is why I was anxious for the upgrade.) I used a test file to reproduce the error, which doesn't seem to occur if the font contains a modest number of glyphs, say a few thousand or less. It is a problem for large fonts (like STKaiti) with more than 32k characters. Can anyone shed light on this situation, and what to do to about it? Many thanks... ---Alan Hoenig
