NAME
iconv – codeset conversion
SYNOPSIS
iconv [-cs] -f frommap -t tomap [file]…
iconv [-cs] -f fromcode [-t tocode] [file]…
iconv [-cs] -t tocode [-f fromcode] [file]…
iconv -l
DESCRIPTION
The iconv command converts the encoding of characters in the input
files from one codeset to another, and writes the results to standard
output. If no input files are given, iconv reads from standard input.
If – appears as an input file name, the iconv command reads standard
input at that point. — can be used to delimit the end of options
(see getopt(3C)).
Options
The iconv command recognizes the following options:
-c Omit any characters that are invalid in the
codeset of the input file from the output. This
is the default.
-f fromcode Identify the codeset corresponding to option
argument fromcode as the codeset that the input
will be converted “from”. The fromcode option
argument must not contain a slash character. If
this option is omitted, the codeset of the current
locale will be used.
-f frommap The frommap option argument must contain a slash
character. It is interpreted as the pathname of a
charmap file which is parsed to determine the
codeset name defined in the charmap file.
-l Write all the supported fromcode and tocode values
to standard output as defined in the iconv
configuration files,
/usr/lib/nls/iconv/system.config.iconv or
/usr/lib/nls/iconv/config.iconv. See iconv(3C)
for details.
-s Suppress any error messages written to standard
error concerning invalid characters. The presence
or absence of -s does not affect the exit status
of iconv.
-t tocode Identify the codeset corresponding to option
argument tocode as the codeset that the input will
be converted “to”. The tocode option argument
must not contain a slash character. If this
option is omitted, the codeset of the current
locale will be used.
-t tomap The tomap option argument must contain a slash
character. It is interpreted as the pathname of a
charmap file which is parsed to determine the
codeset name defined in the charmap file.
The fromcode and tocode names can be any of the base and alias names
listed in the iconv configuration files,
/usr/lib/nls/iconv/system.config.iconv or
/usr/lib/nls/iconv/config.iconv. See iconv(3C) for details and the
configuration files for a list of supported codeset names.
