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.

NAME
iconv - convert text from one character encoding to another SYNOPSIS
iconv [options] [-f from-encoding] [-t to-encoding] [inputfile]... DESCRIPTION
The iconv program reads in text in one encoding and outputs the text in another encoding. If no input files are given, or if it is given as a dash (-), iconv reads from standard input. If no output file is given, iconv writes to standard output. If no from-encoding is given, the default is derived from the current locale's character encoding. If no to-encoding is given, the default is derived from the current locale's character encoding. OPTIONS
-f from-encoding, --from-code=from-encoding Use from-encoding for input characters. -t to-encoding, --to-code=to-encoding Use to-encoding for output characters. If the string //IGNORE is appended to to-encoding, characters that cannot be converted are discarded and an error is printed after conversion. If the string //TRANSLIT is appended to to-encoding, characters being converted are transliterated when needed and possible. This means that when a character cannot be represented in the target character set, it can be approximated through one or several similar looking characters. Characters that are outside of the target character set and cannot be transliterated are replaced with a ques- tion mark (?) in the output. -l, --list List all known character set encodings. -c Silently discard characters that cannot be converted instead of terminating when encountering such characters. -o outputfile, --output=outputfile Use outputfile for output. -s, --silent This option is ignored; it is provided only for compatibility. --verbose Print progress information on standard error when processing multiple files. -?, --help Print a usage summary and exit. --usage Print a short usage summary and exit. -V, --version Print the version number, license, and disclaimer of warranty for iconv. EXIT STATUS
Zero on success, nonzero on errors. ENVIRONMENT
Internally, the iconv program uses the iconv(3) function which in turn uses gconv modules (dynamically loaded shared libraries) to convert to and from a character set. Before calling iconv(3), the iconv program must first allocate a conversion descriptor using iconv_open(3). The operation of the latter function is influenced by the setting of the GCONV_PATH environment variable: * If GCONV_PATH is not set, iconv_open(3) loads the system gconv module configuration cache file created by iconvconfig(8) and then, based on the configuration, loads the gconv modules needed to perform the conversion. If the system gconv module configuration cache file is not available then the system gconv module configuration file is used. * If GCONV_PATH is defined (as a colon-separated list of pathnames), the system gconv module configuration cache is not used. Instead, iconv_open(3) first tries to load the configuration files by searching the directories in GCONV_PATH in order, followed by the system default gconv module configuration file. If a directory does not contain a gconv module configuration file, any gconv modules that it may contain are ignored. If a directory contains a gconv module configuration file and it is determined that a module needed for this conversion is available in the directory, then the needed module is loaded from that directory, the order being such that the first suitable module found in GCONV_PATH is used. This allows users to use custom modules and even replace system-provided modules by pro- viding such modules in GCONV_PATH directories. FILES
/usr/lib/gconv Usual default gconv module path. /usr/lib/gconv/gconv-modules Usual system default gconv module configuration file. /usr/lib/gconv/gconv-modules.cache Usual system gconv module configuration cache. CONFORMING TO
POSIX.1-2001. EXAMPLE
Convert text from the ISO 8859-15 character encoding to UTF-8: $ iconv -f ISO-8859-15 -t UTF-8 < input.txt > output.txt The next example converts from UTF-8 to ASCII, transliterating when possible: $ echo abc B a EUR ac | iconv -f UTF-8 -t ASCII//TRANSLIT abc ss ? EUR abc SEE ALSO
