            Bug ID: 102880
           Summary: Missing chars in rendered PDF
           Product: poppler
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
          Assignee: poppler-bugs at lists.freedesktop.org

Created attachment 134339

PDF which shows the problem

When rendering the attached PDF with actual poppler some chars are not shown.
Looking into it I figured out that the included truetype font has no cmap table
and try the TrueType 'post' table to handle any unmapped characters is not
working correctly because in FoFiTrueType::readPostTable() some chars were
skipped.

With xpdf 4.00 the PDF is shown correctly.

Comparing poppler code of FoFiTrueType::readPostTable() with the xpdf code 4.00
I encountered that this bug was probably introduced with a patch I uploaded for
bug 84270.

But reverting FoFiTrueType::readPostTable() from poppler to the xpdf 4.00 code
doesn't only renders this PDF correctly, it renders also the PDF of bug 84270
correctly.

And since the xpdf 4.00 code is cleaner I would prefer to take over this code
again!
