Created attachment 7972 [details] MissingGlyphs.pdf The attached file MissingGlyphs.pdf contains a table of messages in several languages. If this file is converted to PDF, the glyphs of the lines with the country codes JA, ZH and AR are missing. If the same file is converted to TIFF/G4 or Postscript, everything is OK!
This should clearly be a PDF writer problem, not a PDF interpreter problem.
Fixed in Git commit: 312255297353a9f62b5090e9137586a8ecfc8601 Unfortunately, now that I can see the text, its clear that the Arabic text is not correctly spaced after conversion via pdfwrite. It looks like many of the glyphs have a width of 0. I'll open that as a new bug, and close this one, since the text is no longer missing.
New bug #692621 opened for the spacing problem.
Bug #692621 is now resolved, for complete success two Commits are required: 312255297353a9f62b5090e9137586a8ecfc8601 and b5fa52b7e60a7eb23b77c4fd117ed37eb04263b5
