|Operating system||Unix and Unix-like|
In Unix-like operating systems, iconv (an abbreviation of internationalization conversion) is a command-line program and a standardized application programming interface (API) used to convert between different character encodings. "It can convert from any of these encodings to any other, through Unicode conversion."
Initially appearing on the HP-UX operating system,
iconv() as well as the utility was standardized within XPG4 and is part of the Single UNIX Specification (SUS).
The version of
iconv that is part of the GNU C Library was written by Ulrich Drepper.
Most Linux distributions provide an implementation, either from the GNU Standard C Library (included since version 2.1, February 1999), or the more traditional GNU
libiconv, for systems based on other Standard C Libraries.
Unlike the libraries, the
iconv utility is licensed under GPL in both implementations.
The GNU libiconv implementation is portable, and can be used on various UNIX-like and non-UNIX systems. Version 0.3 dates from December 1999.
Most BSD systems use NetBSD's implementation, first appeared in December 2004.
Currently, over a hundred different character encodings are supported.
Under Microsoft Windows, the iconv library and the utility is provided by GNU's libiconv found in Cygwin and GnuWin32 environments; there is also a "purely Win32" implementation called "win-iconv" that uses Windows' built-in routines for conversion. The iconv function is also available for many programming languages.
iconv -f iso-8859-1
An input file
infile can be converted from ISO-8859-1 to UTF-8 and output to output file
iconv -f iso-8859-1 -t utf-8 <infile >outfile
