The GNU libiconv package provides the basis for character set conversion
of text, for systems that don't use glibc.
It contains an implementation of the iconv() POSIX:2024 API and of the
'iconv' program, in a way that is mostly glibc compatible.
It is now available in version 1.18.
==== New in 1.18 ====
* Many more transliterations, in particular also of Emoji characters.
* The iconv_open function is now POSIX:2024 compliant: it recognizes a
suffix //NON_IDENTICAL_DISCARD in the 'tocode' argument, with the effect
that characters that cannot be represented in the target character set
will be silently discarded. Whereas the suffix //IGNORE in the 'tocode'
argument has the effect of discarding not only characters that cannot be
represented in the target character set, but also invalid multibyte
sequences in the input.
Accordingly, the iconvctl function accepts requests
ICONV_GET_DISCARD_INVALID, ICONV_SET_DISCARD_INVALID,
ICONV_GET_DISCARD_NON_IDENTICAL, ICONV_SET_DISCARD_NON_IDENTICAL.
* The iconv_open function and the iconv program now support multiple suffixes,
such as //TRANSLIT//IGNORE, not only one.
* GB18030 is now an alias for GB18030:2005. A new converter for GB18030:2022
is added. Since this encoding merely cleans up a few private-use-area
mappings, you can continue to use the GB18030 converter, for backward
compatibility. Its Unicode to GB18030 conversion direction has been
enhanced, to help transitioning away from PUA code points.
* When converting from/to an EBCDIC encoding, a non-standard way of
converting newlines can be requested
- at the C level, by calling iconvctl with argument ICONV_SET_FROM_SURFACE
or ICONV_SET_TO_SURFACE, or
- from the iconv program, by setting the environment variable
ICONV_EBCDIC_ZOS_UNIX to a non-empty value.
* Special support for z/OS: The iconv program adds a charset metadata tag to
its output file. (Contributed by Mike Fulton.)
* For conversions from UCS-2, UCS-4, UTF-16, UTF-32, invoking
iconv(cd,NULL,NULL,...) now preserves the byte order state.

Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg --verify libiconv-1.18.tar.gz.sig
The signature should match the fingerprint of the following key:
pub rsa4096 2019-02-12 [SC]
9001 B85A F9E1 B83D F1BD A942 F5BE 8B26 7C6A 406D
uid Bruno Haible (Open Source Development) <br...@clisp.org>
If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.
gpg --recv-keys F5BE8B267C6A406D
As a last resort to find the key, you can try the official GNU
keyring:
wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
gpg --keyring gnu-keyring.gpg --verify libiconv-1.18.tar.gz.sig
