Description skierpage 2012-04-03 00:05:36 UTC

In Kubuntu 12.04 pre-release Okular didn't show any text in http://www.toyota-global.com/sustainability/report/sr/10/pdf/sustainability_report10.pdf

I turned on all okular flags in kdebugdialog, and get a lot of
	PDFGeneratorPopplerDebugFunction: [Poppler] "Error: Missing language pack for 'Adobe-Japan1' mapping"
	PDFGeneratorPopplerDebugFunction: [Poppler] "Error: Unknown font tag 'C0_0'"
	PDFGeneratorPopplerDebugFunction: [Poppler] "Error (83NNNN): No font in show"
errors.

The fix was to install the poppler-data package. Even though this is an English-language document, it still depends on some special font encoding information. Ubuntu is supposedly going to install poppler-data for all languages (https://bugs.launchpad.net/ubuntu/+bug/893920), but it seems this workaround should be mentioned in the Okular FAQ to save time and head-banging :-)

I suggest in http://okular.kde.org/faq.php under "Running Okular" add
  On Linux, I don't see any text in a PDF, what should I do?
Answer:
  You may need to ensure you have the package "poppler-data" installed. In many Linux distributions this package has additional font encoding information used by CJK (Chinese/Japanese/Korean) fonts. Even if a PDF only uses Western characters, it may need this information.

Imo, I'd argue this is a distro issue.  http://poppler.freedesktop.org/ includes the statement:
Besides poppler you are also going to need poppler encoding data: poppler-data-0.4.5.tar.gz
so, distros ought to add appropriate dependencies to ensure poppler-data is present along with the poppler libraries.

(Fwiw, we went through the issue in fedora awhile back, and added said dependency after consulting poppler upstream)
