Converting PDF page to image missing accentuated characters

I’m converting page 3 from this PDF to a JPEG:
https://drive.google.com/file/d/0B7PFCA ... sp=sharing
This is the resulting image:
https://drive.google.com/file/d/0B7PFCA ... sp=sharing
I'm using this command:
Code: Select all
convert -verbose -quality 85 -density 150 multi.pdf[2] -resample 150 1.jpg
No errors are displayed in verbose mode.
The text is in Portuguese, but accentuated characters from the text are missing. For example the title should be "Gestão da inovação" instead of "Gest o da inovaç o". This happens in all pages from this PDF.
I have checked and I have freetype in the DELEGATES tag.

It converts fine for me, IM v6.8.9-0 on Windows 8.1, using Ghostscript v9.10. What are you running? If old software, an upgrade may cure it.

Yeah, that's over 1000 versions old, and many years. I suggest you upgrade. Do Ghostscript as well.
EDIT: We cross-posted. Did you also upgrade GS?

Updating ghostscript solved the problem. Thank you snibgo!

Hi, I am having the same issue. I am using Uonze PDF to test this.
I was using ImageMagick 6.7.7 and Ghostscript 9.10 on an Ubuntu 14.04 server and I was getting the same errors. So I tried updating, I manually installed ImageMagick 6.8.9-10. Later, I added Ubuntu's 15.04 repository to apg-get so I was able to install Ghostscript 9.15. But still, I have these errors with accent characters.
I tried using /convert command or /gs directly to convert the PDF and the issue is always there. My latest attempts was using these commands:
Code: Select all
gs -dSAFER -dBATCH -dNOPAUSE -sDEVICE=jpeg -sOutputFile=gs-test.jpg -dFirstPage=3 -dLastPage=3 -dRENDERTTNOTDEF=1 multi.pdf
Code: Select all
/opt/imagemagick-6.8/bin/convert multi.pdf[2] -alpha off -resize '1024x1024' -quality '75' im-test.jpg
These are the versions installed:
Code: Select all
gs -v
GPL Ghostscript 9.15 (2014-09-22)

Any ideas on how to fix this?
EDIT: I installed ImageMagick on a Mac OS, and it's converting the PDF file correctly. I'm starting to think it's a problem with FreeType library or something related to that. As you can see, freetype is not declared on the Delegates of ImageMagick 6.8.9 that I manually installed. But it't declared on the ImageMagick 6.7.7 from the Ubuntu's official repository:
Code: Select all
$ convert -version

The problem was the Ghostscript version, 9.15 is not enough. Version 9.16 fixed the error.

By the way, how did you update the version 6.7.7 to 6.8 in Ubuntu?
I tried to follow some of the suggestions present on this website, but those did not work.
Could you please give a clue on how to update the version in Ubuntu 14.something?

You can download the official binary package for linux x64 at Ghostscript website:
http://downloads.ghostscript.com/public/binaries/
I, personally, just replaced the /usr/bin/gs binary with the new one.
If you need more info, check this post on askubuntu:
