.B Character sets:
.PP
File names are strings of non-zero bytes with 8 bit each. Unfortunately
the same byte string may appear as different peculiar national characters
on differently nationalized computers.
The meanings of byte codes are defined in \fBcharacter sets\fR which have
names. Shell command iconv -l lists them.
.br
Character sets should not matter as long as only alphanumeric characters are
used for file names or as long as the computer which runs xorriso uses the
same character set as the computer which wrote the loaded image and those
computers which shall read the newly emerging ISO image.
Outside these constraints it may be necessary to let xorriso convert byte
codes.
.br
There is an input conversion from input character set to the local character
set which applies when an ISO image gets loaded. A conversion from local
character set to the output character set is performed when a new
image tree gets written. The sets can be defined independently by options
-in_charset and -out_charset. Normally one will have both identical, if ever.
.br
xorriso expects and uses the local character set for command arguments
and file name output. Other character sets will only be in effect on media.
