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.

AUTHOR

       iconv was written by Ulrich Drepper as part of the GNU C Library.

       This man page was written by Joel Klecker <espy@debian.org>, for the Debian GNU/Linux system.
