Description Gero Kunter 2008-05-08 18:23:47 UTC

Version:           0.6.3 (using KDE 4.0.3)
Installed from:    SuSE RPMs
OS:                Linux

When I generate plots in R and save them as PDF files, Okular doesn't display the correct symbols. In KPDF, everything works as expected. I'll attach an example PDF file, as well as screenshots from Okular and KPDF.

Works here.

Which Poppler-Qt4 version do you have?
Open the font information of the document in both KPDF and Okular (File -> Properties -> Fonts), do you see the same filenames for the fonts in both the apps?

Comment 5 Gero Kunter 2008-05-08 21:55:19 UTC

Poppler-Qt4 is version 0.5.4-101.4.

The problem seems to be the mapping of font ZapfDingbats:

KPDF uses /usr/share/ghostscript/fonts/d050000.pfb (indeed a DingBats font)
Okular uses /usr/share/fonts/truetype/albw.ttf (which is Albany AMT)

Is this a distribution bug, then?

This is *really* old, please use 0.8.x, or if it is not possible, at least 0.6.x.

Uhm, yes and no; the font subsitution is a fontconfig configuration, and probably every distro configures its default.

Hello Gero,

do you still have this problem with a more recent version of Poppler?

Comment 8 Gero Kunter 2008-08-27 09:17:10 UTC

Hi Pino,

sorry for sort of abandoning this bug report for too long. Here's my update:

Yes, Okular still displays the wrong symbols in PDF files such as the attached, even with pre

[sorry, wrong key :(]

Okular (0.7) still displays the wrong symbols in PDF files such as the attached file, even with pretty recent versions of Poppler-Qt4 (0.8.5).

Comment 10 Pino Toscano 2008-10-12 02:28:42 UTC

sorry Gero for taking too long on this report...

it seems the problems persists for you even with more recent versions of Poppler... then, it should be better to report it to the Poppler bug tracking system (https://bugs.freedesktop.org, "poppler" product) so it can be tracked better than it could here.
(Marking as INVALID as it is not an Okular problem -- we don't have NOTKDE yet.)

Thanks for the feedback and for understanding.
