Evince displays some summation symbols incorrectly in pdfs

[Alfonso E. Romero]

Binary package hint: evince

When displaying some LaTeX generated pdfs the Summation symbol is printed as a big filled dot, instead of the sigma symbol. In particular, with some papers of the JMLR journal ( http://jmlr.org which is a free journal), this happen almost everywhere. The product symbol (the big Pi) is also displayed incorrectly.

A example of this is: http://www.jmlr.org/papers/volume11/mann10a/mann10a.pdf

This does not happen in xpdf, as it can be seen in the attached image (where one can notice what is displayed [in evince] and what should be displayed [in xpdf]).

This happens in Ubuntu 9.10 Karmic Koala, with evince 2.28.1-0ubuntu1.2 0.

This is fixed in Ubuntu 10.04 "Lucid Lynx" alpha 3, updated to the latest Ubuntu poppler package.

See attached screenshot.

closing the bug since I think that was the intend

[madbiologist (me-again)]

OK, thanks. I wasn't sure if we had to wait for 10.04 final to be able to mark the fix as "released", or not.

[Sebastien Bacher (seb128)]

the bugs are closed when a fixed version is uploaded to the unstable distribution usually

[Alfonso E. Romero (alfonsoeromero)]

In fact, it is still happening in Ubuntu 10.04. In this paper: http://www.jmlr.org/papers/volume9/balakrishnan08a/balakrishnan08a.pdf page 2, formula one, there is no summation symbol (and a horrible division one instead). Can anyone confirm that the version in Ubuntu 10.04 was not supposed to be fixed. If it was, the bug is not still solved...

[Sang Oh (yagwangbyul)]

I can confirm that 10.04 has the same problem.

This pdf : http://jmlr.csail.mit.edu/papers/volume9/banerjee08a/banerjee08a.pdf

Shows up like this : http://img97.imageshack.us/img97/1914/screenshotbanerjeemodel.png

Other symbols are wrong too, infinity symbol for example.

The file in comment #7 displays fine here - see attached screenshot.

Installing poppler-data might fix this for you.

[Alfonso E. Romero (alfonsoeromero)]

The file in #7 does not display well for me (see attached image), neither the one I sent on the first post. I have evince 2.30.1, and have just installed poppler-data (which was not installed).

[madbiologist (me-again)]

That's odd. Have you rebooted after installing poppler-data?

My package versions are as follows:

evince 2.30.1-0ubuntu3
poppler 0.12.4-0ubuntu4
poppler-data 0.4.0-2
libcairo2 1.8.10-2ubuntu1

I have a 32 bit system here.

[Alfonso E. Romero (alfonsoeromero)]

Okay, mine are those

evince 2.30.1-0ubuntu3
poppler-data 0.4.0-2
libcairo2 1.8.10-2ubuntu1
libpoppler5 0.12.4-0ubuntu4

Which all seems to be the same. I also rebooted, and things are still wrong. 32 bit system too.

Which I have just noticed (I didn't tested it until now) is that this bug happens exactly the same way in Okular (version 0.10.2), but not in xpdf (3.0.2).

[madbiologist (me-again)]

Thanks. I've got no idea why it works for me and not for you, given that we have the same package versions. Unless it's got something to do with having the system set to a Spanish locale and/or language, but I wouldn't have thought so.

I think we'll have to wait for someone else with more expertise to assist us.

I can reproduce this, with 64bit ubuntu 10.04,

$ evince --version
Visualizador de Documentos do GNOME 2.30.3

$ xpdf -v
xpdf version 3.02
Copyright 1996-2007 Glyph & Cog, LLC

With poppler-data installed. I think it's probably a font issue, althougj this is hard to verify.

[Patrick Bouffard (patrick-m-bouffard)]

I am also seeing this in Ubuntu 10.10 64-bit, with poppler-data installed.

[Alexandre Passos (alexandre-tp)]

After upgrading to 10.10 I can still reproduce this. Maybe it has something to do with locales?

[Alexandre Passos (alexandre-tp)]

This solution (removing ttf-symbol-replacement) worked! http://<email address hidden>/msg2340247.html

[Alfonso E. Romero (alfonsoeromero)]

Hello everybody. Alexandre has hit the key, the original problem has also dissapeared for me. Everything now runs fine! :)
