             Bug #: 50496
           Summary: Cairo-generated PDF displays incorrectly with Adobe
                    Reader and Ghostscript
    Classification: Unclassified
           Product: cairo
           Version: 1.10.2
          Platform: All
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: pdf backend
        AssignedTo: ajohnson at redneon.com
        ReportedBy: till.kamppeter at gmail.com
         QAContact: cairo-bugs at cairographics.org

See the following Ubuntu bug


The file attached there (also attached here) is printed with evince, which uses
Cairo to generate the PDF output stream which gets sent to CUPS. There
Ghostscript renders it and on the printout symbols in the formulas are missing.

I have reproduced it as follows:

Opened the original PDF file (attached) with evince, File/Print, "Print to
file", PDF as output format, only page 60. This gives the (also attached)
sample page. If you display this page with Adobe Reader or Ghostscript you will
see the missing symbols ("(", ")", "-", ",") in the formulas, especially S(t)
in the upper left part, or S(i_0, i_1, i_2, i_3) in the middle-left.

Only Poppler displays the sample page correctly.

As even the Adobe software does not display the page correctly, we assume the
PDF to be broken and therefore a bug in Cairo.
