            Bug ID: 297350
          Severity: normal
           Version: 0.14.1
          Priority: NOR
          Assignee: okular-devel at kde.org
           Summary: Okular FAQ should mention dependency on poppler-data
                    package
    Classification: Unclassified
                OS: Linux
          Reporter: skierpage at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: okular

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.
