Description Georg Schlisio 2012-09-13 19:04:57 UTC

if viewing pdf [1] on page 4 it says '\mu^+ on Cu' (using LaTeX-Syntax for special symbols) what is expected behavior while in [2] at the same place it says '\propto^+ on Cu'. If text is marked with right click, search options pop up indicating correct search for '\mu+'.
Only difference between pdfs i can see is that [1] uses pdf v 1.5 and [2] uses pdf v. 1.4.
correct decryption in search option indicates, that this is an decryption error of pdf v 1.4.

[2] http://pdg.lbl.gov/2011/reviews/rpp2011-rev-passage-particles-matter.pdf

Reproducible: Always

Steps to Reproduce:
1. open pdf
2. find wrong symbol (directions above)
3. mark with right-click to see searching popup
Actual Results:  
\propto istead of \mu

Expected Results:  
\mu instead of \propto

which poppler library version are you using?

Comment 2 Albert Astals Cid 2012-09-13 21:51:45 UTC

Changing to needsinfo

Comment 3 Georg Schlisio 2012-09-14 07:30:45 UTC

using poppler 0.20.3 (from standard arch repo package).

Comment 4 Albert Astals Cid 2012-09-15 18:26:06 UTC

Hmmmmm, interesting, maybe i'm not understanding where you say the wrong data appears, could you attach a screenshot showing the problem?

Comment 5 Georg Schlisio 2012-09-16 07:00:20 UTC

Created attachment 73955 [details]
screenshot illustrating my problem

Comment 6 Albert Astals Cid 2012-09-16 13:42:10 UTC

What's the "File->Properties->Fonts" value for the Symbol font in the pdf that displays that wrong?

Comment 7 Georg Schlisio 2012-09-16 13:50:30 UTC

Symbol Typ 1 ~/.fonts/symbol.tff

what should be the value there?
there ale about 25 partly embedded fonts, but symbol, times-italic and times-roman have a local file path to ~.font/

Comment 8 Albert Astals Cid 2012-09-16 13:53:06 UTC

That's not a correct font for the Symbol font replacement, please configure your system so that a valid symbol font replacement is used http://freedesktop.org/wiki/Software/poppler contains some information on how to do it, i can't guarantee the information is correct, but i'm sure the internet is full of information on how to tweak your fontconfig configuration.
