--iconv=CONVERT_SPEC
Rsync can convert filenames between character sets using this option.
Using a CONVERT_SPEC of lq.rq tells rsync to
look up the default character-set via the locale setting. Alternately,
you can fully specify what conversion to do by giving a local and a
remote charset separated by a comma in the order --iconv=LOCAL,REMOTE,
e.g. --iconv=utf8,iso88591. This order ensures that the option will
stay the same whether you're pushing or pulling files. Finally, you
can specify either --no-iconv or a CONVERT_SPEC of lq-rq to turn off
any conversion. The default setting of this option is site-specific,
and can also be affected via the RSYNC_ICONV environment variable.
