xorrisofs: Charset

 
 5.10 Character sets
 ===================
 
 Character sets should not matter as long as only english alphanumeric
 characters are used for file names or as long as all writers and readers
 of the medium use the same character set.  Outside these constraints it
 may be necessary to let xorriso convert byte codes.
 A conversion from input character set to the output character set is
 performed when an ISO image gets written.  Vice versa there is a
 conversion from output character set to the input character set when an
 ISO image gets loaded.  The sets can be defined by options
 -input-charset and -output-charset, if needed.
 
 -input-charset character_set_name
      Set the character set from which to convert disk file names when
      inserting them into the ISO image.
 
 -output-charset character_set_name
      Set the character set from which to convert names of loaded ISO
      images and to which to convert names when writing ISO images.
