ICONVCONFIG(8)            (2020-08-13)             ICONVCONFIG(8)

          iconvconfig - create iconv module configuration cache

          iconvconfig [options] [directory]...

          The iconv(3) function internally uses gconv modules to con-
          vert to and from a character set.  A configuration file is
          used to determine the needed modules for a conversion.
          Loading and parsing such a configuration file would slow
          down programs that use iconv(3), so a caching mechanism is

          The iconvconfig program reads iconv module configuration
          files and writes a fast-loading gconv module configuration
          cache file.

          In addition to the system provided gconv modules, the user
          can specify custom gconv module directories with the envi-
          ronment variable GCONV_PATH.  However, iconv module configu-
          ration caching is used only when the environment variable
          GCONV_PATH is not set.

               Do not search the system default gconv directory, only
               the directories provided on the command line.

          -o outputfile, --output=outputfile
               Use outputfile for output instead of the system default
               cache location.

               Set the prefix to be prepended to the system pathnames.
               See FILES, below.  By default, the prefix is empty.
               Setting the prefix to foo, the gconv module configura-
               tion would be read from foo/usr/lib/gconv/gconv-modules
               and the cache would be written to
