Iconv

Initially appearing on the HP-UX operating system,{{cite web|url=http://docstore.mik.ua/manuals/hp-ux/en/B2355-60130/iconv.3C.html|title=iconv(3C)|website=docstore.mik.ua|access-date=21 April 2018}}iconv() as well as the utility was standardized within XPG4 and is part of the Single UNIX Specification (SUS).

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{{cite web|title=glibc: iconv/iconv.c|url=https://sourceware.org/git/?p=glibc.git;a=blob;f=iconv/iconv.c|access-date=30 November 2016}}{{Dead link|date=January 2020 |bot=InternetArchiveBot |fix-attempted=yes }} 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.{{cite web|title=glibc: iconv/iconv_prog.c|url=https://sourceware.org/git/?p=glibc.git;a=blob;f=iconv/iconv_prog.c|access-date=30 November 2016}}{{Dead link|date=January 2020 |bot=InternetArchiveBot |fix-attempted=yes }}

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.

The musl C library implements the iconv function with support for all encodings specified by the WHATWG Encoding Standard.

Currently, over a hundred different character encodings are supported in the GNU variant.

Under Microsoft Windows, the iconv library and the utility is provided by GNU's libiconv found in Cygwin{{cite web|title=Cygwin Package Search: libiconv |url=https://cygwin.com/cgi-bin2/package-grep.cgi?grep=libiconv |access-date=30 November 2016 |archive-url=https://archive.today/20161130001530/https://cygwin.com/cgi-bin2/package-grep.cgi?grep=libiconv |archive-date=30 November 2016 |url-status=dead |df=dmy-all }} and GnuWin32{{cite web|url=http://gnuwin32.sourceforge.net/packages/libiconv.htm|title=LibIconv for Windows|website=gnuwin32.sourceforge.net|access-date=21 April 2018}} environments; there is also a "purely Win32" implementation called "win-iconv" that uses Windows' built-in routines for conversion.{{cite web|title=win32-iconv|url=https://github.com/win-iconv/win-iconv|website=GitHub|access-date=30 November 2016}} The iconv function is also available for many programming languages.

The {{Mono|iconv}} command has also been ported to the IBM i operating system.{{cite web |title=IBM System i Version 7.2 Programming Qshell |language=en |author=IBM |website=IBM |author-link=IBM |url=https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_74/rzahz/rzahzpdf.pdf?view=kc |access-date=2020-09-05 }}

stdin can be converted from ISO-8859-1 to current locale and output to stdout using:{{cite web|url=http://www-01.ibm.com/support/knowledgecenter/ssw_aix_53/com.ibm.aix.cmds/doc/aixcmds3/iconv.htm|title=IBM Knowledge Center|website=www-01.ibm.com|access-date=21 April 2018}}

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 -o
