ICONV(1) Linux User Manual ICONV(1) 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 sev- eral similar looking characters. Characters that are outside of the target character set and cannot be transliterated are replaced with a question 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, non-zero 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 mod- ule configuration cache file created by iconvconfig(8) and then, based on the configuration, loads the gconv modules needed to per- form 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 search- ing 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 mod- ule 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 providing 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 ß α € àḃç | iconv -f UTF-8 -t ASCII//TRANSLIT abc ss ?
