Title:
Ghostscript 9.22 garbles characters when rendering certain PDFs
Status in ghostscript package in Ubuntu:
Fix Released
Bug description:
Certain PDFs such as
https://www.cl.cam.ac.uk/downloads/ring/ring-2014-05.pdf
render in ghostscript 9.22~dfsg+1-0ubuntu1.1 (as found on a fresh
Ubuntu 18.04.1 LTS install) with almost all characters replaced by
either random characters or empty rectangles. Same problem in gv.
The same PDFs render correctly on older Ghostscript versions (e.g.,
Ghostscript 9.18 from Ubuntu 16.04), as well as with other PDF viewers
(e.g., evince, okular, acroread). The PDFs pass the Adobe Acrobat
"preflight" checks.
How to reproduce (X11 required):
$ wget https://www.cl.cam.ac.uk/downloads/ring/ring-2014-05.pdf
$ gs -dSAFER ring-2014-05.pdf
Expected behaviour: Journal title (big font, top of page 1) should
read "The Ring"
Actual behaviour: Journal title (big font, top of page 1) reads "7KH
5LQJ"
There are no error or warning messages.
[A very similar PDF (same fonts, just produced by a different Adobe InDesign
/ PDF Library version) that does not exhibit this problem is e.g.
https://www.cl.cam.ac.uk/downloads/ring/ring-2014-01.pdf
and other example files can be found in the same https directory. ]
