PDF-Reader no longer able to display mathematical symbols in PR 1.2
 

The PDF-Reader used to work perfectly for me to display documents containing mathematical formulae, for instance scientific papers from http://arxiv.org. After the upgrade to PR 1.2, it doesn't display any math any longer! :eek:

Other apps capable of displaying pdf files such as xournal don't have any problems after the upgrade, while the standard PDF reader, which I liked very much, is now almost completely useless for me.

Can anyone verify this problem? E.g., by opening a random physics preprint from arxiv.org, like the following short pdf file http://arxiv.org/pdf/1005.1132

Anyone any idea how to fix that? Could crucial files have been inadvertently removed from PR1.2 that would still be available in the older firmware?

UPDATE: Fixed finally in PR1.3.

yup, confirming that most of the math symbols are missing...wondering which font got removed from PR1.2...

Re: PDF-Reader no longer able to display mathematical symbols in PR 1.2
 

uhm no, in fact it's possible that PDF-Reader doesn't read the embedded fonts anymore (by looking at the properties of the file (from acrobat) it looks like most of the symbols are from embedded fonts, and not from system-wide fonts...

Re: PDF-Reader no longer able to display mathematical symbols in PR 1.2
 

Thanks for confirming that! Curiously xournal still can display everything fine, and that app certainly doesn't come with additional specialized fonts! I always thought that pdf files have their fonts embedded somehow.

Re: PDF-Reader no longer able to display mathematical symbols in PR 1.2
 

If the pdf reader doesn't look at the embedded fonts any longer, I guess there is no easy fix.

Strangely enough, I didn't see osso-pdf-viewer in the changelog.

Evince also displays them without a problem.

Re: PDF-Reader no longer able to display mathematical symbols in PR 1.2
 

I know! I'm using it through Easy Debian in fact. Would it be possible to have evince opened automatically when viewing a pdf with microB?

Since osso-pdf-viewer is hopefully open source, is there a way to have that fixed by the community, and not have to wait for PR 1.3 now? :rolleyes:

What if we install Droid fonts? can that solve the problem?
Also I've noticed pdf viewer became less stable I tried to open big pdfs like i was doing in pr 1.1.1 but now it showed me a warning not enough memory and opened files after 10 seconds or so

Re: PDF-Reader no longer able to display mathematical symbols in PR 1.2
 

I've already have Droid Fonts and it stlll has this issue.Unless the pdf reader specifically references Droid fonts i dont think it will use them.

Re: PDF-Reader no longer able to display mathematical symbols in PR 1.2
 

I also already have Droid fonts and it didn't help. If the problem is simply that embedded fonts are not used, while the viewer in principle can handle them, one would have to find out what stopped that.
