      The gconv libraries are used to convert between different

      character sets (charsets).

      Say 'y' if you need to store and/or display different charsets.

      Set to the list of gconv libraries to copy.

      Leave empty to copy all gconv libraries.

      Specify only the basename of the libraries, leave

      out the .so extension. Eg.:

        IBM850 ISO8859-15 UNICODE

      Note: the full set of gconv libs are ~8MiB (on ARM).
