 Added the --iconv option, which allows rsync to convert filenames from
      make this feature available as long as your system has iconv_open().
      If compilation fails, specify --disable-iconv to configure, and then
      default, you can specify --enable-iconv=CONVERT_STRING with the default
      value for the --iconv option that you wish to use.  For example,
      "--enable-iconv=." is a good choice.  See the rsync manpage for an
      explanation of the --iconv option's settings.
      set that is used during an --iconv transfer to/from a daemon module.  You
      can also set your daemon to refuse "no-iconv" if you want to force the
      client to use an --iconv transfer (requiring an rsync 3.x client).
