iconv
ICONV(1) Debian GNU/Linux ICONV(1)NAME
iconv - Convert encoding of given files from one encoding to another
SYNOPSIS
iconv -f encoding [-t encoding] [inputfile]...
DESCRIPTION
The iconv program converts the encoding of characters in inputfile, or from the standard input if no filename is specified, from one coded
character set to another. The result is written to standard output unless otherwise specified by the --output option.
--from-code, -f encoding
Convert characters from encoding.
--to-code, -t encoding
Convert characters to encoding. If not specified the encoding corresponding to the current locale is used.
--list, -l
List known coded character sets.
-c Omit invalid characters from output.
--output, -o file
Specify output file (instead of stdout).
--silent, -s
Suppress warnings, but not errors.
--verbose
Print progress information.
--help, -?
Give help list.
--usage
Give a short usage message.
--version, -V
Print program version.
ENCODINGS
The values permitted for --from-code and --to-code can be listed by the iconv --list command, and all combinations of the listed values are
supported. Furthermore the following two suffixes are supported:
//TRANSLIT
When the string "//TRANSLIT" is appended to --to-code, transliteration is activated. This means that when a character cannot be
represented in the target character set, it can be approximated through one or several similarly looking characters.
//IGNORE
When the string "//IGNORE" is appended to --to-code, characters that cannot be represented in the target character set will be
silently discarded.
