NAME
iconv - code set conversion utility
SYNOPSIS
iconv [-cs] -f frommap -t tomap [file]...
iconv -f fromcode [-cs] [-t tocode] [file]...
iconv -t tocode [-cs] [-f fromcode] [file]...
iconv -l
DESCRIPTION
The iconv utility converts the characters or sequences of
characters in file from one code set to another and writes the results to standard output. If no conversion exists fora particular character, an implementation-defined conversion
is performed on this character. The list of supported conversions and the locations of theassociated conversion tables are provided in the iconv(5)
manual page. OPTIONS The following options are supported:-c Omits any characters that are invalid in
the codeset of the input file from theoutput. When -c is not used, the results
of encountering invalid characters in the input stream depend on the specifiedcodesets for the conversion. Invalid char-
acters can be either those that are not valid characters in the codeset of the input file or those that have no corresponding character in the codeset of the output file. The presence or absenceof -c does not affect the exit status of
iconv. When fromcode is specified for the
fromcodeset of the -f option or tocode is
specified for the tocodeset of the -t
option, the specification of -c may be
ignored.-f fromcodeset Identifies the code set of the input file.

option-argument are recognized:
fromcode The fromcode option-argument
must not contain a slash(/) character. It is inter-
preted as the name of one of the codeset descriptions.frommap The frommap option-argument
must contain a slash charac-
ter. It is interpreted as the pathname of a charmap file as defined in charmap(5). If the pathname does not represent a valid, readable charmap file, the results are undefined. If this option is omitted, the codeset of the current locale is used.-l Writes all supported fromcode and tocode
values to standard output.-s Suppresses any messages written to stan-
dard error concerning invalid characters.When -s is not used, the results of
encountering invalid characters in the input stream depend on the specifiedcodesets for the conversion. Invalid char-
acters can be either those that are not valid characters in the codeset of the input file or those that have no corresponding character in the codeset of the output file. The presence or absenceof -s does not affect the exit status of
iconv. When fromcode is specified for the
fromcodeset of the -f option or tocode is
specified for the tocodeset of the -t
option, the specification of -s may be
ignored.-t tocodeset Identifies the code set used for the out-
put file. The following two forms of thetocodeset option-argument are recognized:

the name of one of the codeset descriptions.tomap The tomap option-argument must
contain a slash character. It is interpreted as the pathname of acharmap file as defined in char-
map(5). If the pathname does not represent a valid, readable charmap file, the results are undefined. If this option is omitted, the codeset of the current locale is used.If either -f or -t represents a charmap file but the other
does not, or is omitted, or if both -f and -t are omitted,
iconv fails as an error.
OPERANDS The following operands are supported: file A path name of an input file. If no file operandsare specified, or if a file operand is '-', the
standard input is used.EXAMPLES
Example 1 Converting and storing files The following example converts the contents of file mail1 from code set 8859 to 646fr and stores the results in file mail.local:example% iconv -f 8859 -t 646fr mail1 > mail.local

NOTES Make sure that both charmap files use the same symbolic names for characters the two codesets have in common.The output format of the -l option is unspecified. The -l
option is not intended for shell script usage.When fromcode or tocode is specified for the codeset conver-
sion, iconv uses the iconv_open(3C) function. If
iconv_open(3C) fails to open the specified codeset conver-
sion, iconv searches for an appropriate conversion table. As
for the supported codeset conversion by iconv_open(3C),
please refer to iconv(5) and iconv_locale(5).
