When it did show, it is/was sort of grainy.

If there is some sort font which is missing, it should show in some understandable manner.

The poster in question can be found at http://madsrh.googlepages.com/poster.pdf
I can confirm the error messages and the graininess. However, please note that the graininess goes away when zooming in... Opened also in acroread 8, no errors, no graininess (however, zoom in to 150% and the graininess goes away also in evince).
The fonts included are "Calibri" and "Ubuntu-Title""

Define long time please, 1 second, 1 minute, 1 hour, 1 day?

The font grainyness seem present only in the cairooutputdev, poppler master is supposed to have some fixes about fonts in the cairooutputdev but i can't test it because it needs a too new cairo, Carlos can you please test?

4.5s doesn't seem "too long" to me, moving to cairo outputdev component as the font problem is the only problem i really see in this pdf.

I stumbled over this bug report while searching the web on 
with the error message 
"Error: Illegal entry in bfchar block in ToUnicode CMap"
I saw this message displayed while trying to view a PDF file
generated by Adobe Indesign CS4 (Adobe PDF Library 9.0) with
evince (Ubuntu 9.4 Jaunty with poppler-utils 0.10.5-1ubuntu2).

In my case this particular PDF displays wrong results
(compared to what Adobe Acrobat 8.0 shows and what the creator
of this particular PDF obviously intended):  Certain text
is missing!  Unfortunately I'm not allowed to attach this
particular problematic PDF because it contains confidential info.
Comment 5 Albert Astals Cid 2009-09-17 14:08:29 UTC
Peter, without the pdf there is nothing we can do, if you send it to me i can have a look and put it on my files to never share. Otherwise we can't do anything.
Comment 6 Carlos Garcia Campos 2010-01-25 02:56:06 UTC
It takes mostly the same time in splash and cairo backend, I see the same error messages with both too and the fonts rendering issue is fixed in git master now (bug #5589). Do we move this to general because of the rendering time? or just close it as fixed because of the font rendering?

Hi all, 
I am on Debian sid now and this issue is still there. 

Error: Illegal entry in bfchar block in ToUnicode CMap

It does not matter what app I use get the same issue. 


$ epdfview cellit.pdf 
Error: Illegal entry in bfchar block in ToUnicode CMap


$ xpdf cellit.pdf 
Error: Illegal entry in bfchar block in ToUnicode CMap

and it takes quite a bit of time to open up (more than a minute) the file. This is on Pentium Dual-core. The error comes out multiple times. 

One can find the pdf I was opening at http://cellit.co.in/ui_images/magazines/pdf/Magazine-1-2012-33.pdf . I just renamed it to cellit so I remember.
