      The additional package consists of encoding files for use with
      <application>Poppler</application>. The encoding files are optional and
      <application>Poppler</application> will automatically read them if they
      are present. When installed, they enable
      <application>Poppler</application> to render CJK and Cyrillic properly.

        This package can be optionally built with support for only one version
        of Qt4 or Qt5 or without any Qt support. You can selectively disable
        support for one or both, see "Command Explanations" section, below.
      </para>

      Install <application>Poppler</application> by running the following

      In order to run the test suite, some testcases are needed and can
      be obtained only from a git repository. The command to download
      them is:

      Then issue: <command>LC_ALL=en_US.UTF-8 make check</command>. It seems
      that only the Qt4/5 libraries are tested.
