Description Piotr Strzelczyk 2008-10-09 05:08:40 UTC

Uploaded you'll find two sample PDF files:

* one of them, SAMPLE1.pdf (created by XeTeX), apparently properly formed
  (Acrobat Reader and GS display it properly) -- cannot be repeatedly
  distilled using Ghostscript -- GS (8.63) reports the following error
  (output other than pdfwrite work OK):

* the second sample resulted from the first one by removing
  the entry /ToUnicode from the font dictionary -- this PDF
  can be distilled without problems

This report probably is confirmation of bug 689842.

This sample can be distilled

Comment 3 Ken Sharp 2008-10-09 05:17:50 UTC

Going by the comments from Alex in bug #689842, this is almost certainly the
same problem, and should be a PDF Interpreter problem, not a PDF writer issue.

I won't mark it as a duplicate, because I haven't checked.

Comment 4 Alex Cherepanov 2008-10-09 06:30:55 UTC

This case of CMap syntax abuse is worse than anything we have seen before.

/CMapName //usr/local/share/fonts/lm-o/lmroman10-regular.otf,000-UTF16 def

However the fix is still the same: search for keywords and ignore
all PostScript cruft.
