In Unix and Unix-like operating systems, iconv (an abbreviation of internationalization conversion) [2] is a command-line program [3] and a standardized application programming interface (API) [4] used to convert between different character encodings. "It can convert from any of these encodings to any other, through Unicode conversion." [5]
History
Initially appearing on the
HP-UX operating system,
[6]iconv() as well as the utility was standardized within
XPG4 and is part of the
Single UNIX Specification (SUS).
Implementations
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.
The iconv function
[7] on both is licensed as
LGPL, so it is linkable with closed source applications.
Unlike the libraries, the iconv utility is licensed under
GPL in both implementations.
[8]
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.
The uconv utility from International Components for Unicode provides an iconv-compatible command-line syntax for transcoding.
Most BSD systems use NetBSD's implementation, which first appeared in December 2004.
Support
Currently, over a hundred different character encodings are supported. [5]
Ports
Under Microsoft Windows, the iconv library and the utility is provided by GNU's libiconv found in Cygwin [9] and GnuWin32 [10] environments; there is also a "purely Win32" implementation called "win-iconv" that uses Windows' built-in routines for conversion. [11] The iconv function is also available for many programming languages.
The iconv command has also been ported to the IBM i operating system. [12]
Usage
stdin can be converted from
ISO-8859-1 to current locale and output to
stdout using:
[13]
iconv -f iso-8859-1
An input file infile can be converted from ISO-8859-1 to UTF-8 and output to output file outfile using:
iconv -f iso-8859-1 -t utf-8 <infile> -o <outfile>
