 Character set support
 =====================
 
-Mutt has extensive support for doing character set conversions.  To
-use this, you'll need the proper character set definition files.
-
-If these files are already installed on your system (glibc 2.0
-includes them), you can tell the configure script this by using the
---with-charmaps option.  As an argument, it takes the directory in
-which the character set definition files have been installed.  By
-default, configure looks into /usr/share/i18n/charmaps.
-
-If these files are not present on your system, you can download a
-charmaps tar-ball from the same place from which you got mutt (e.g.,
-ftp.guug.de/pub/mutt/). Unpack it under the mutt toplevel source
-directory, and re-configure mutt.  configure will detect this; the
-character set definition files should be automatically installed in
-the proper place.
+Mutt no longer contains functions for doing character set conversion.
+Instead, it expects the iconv functions (iconv_open, iconv,
+iconv_close) to be provided. Most up-to-date systems provide these
+functions, often as part of the C library. If you are installing Mutt
+on a system which does not have them, it is recommended that you
+install Bruno Haible's portable libiconv library, which you can obtain
+from:
+
+ftp://ftp.ilog.fr/pub/Users/haible/gnu/
+
+Even if your system does provide the iconv functions, you might want
+to install libiconv, as some systems provide only a very limited
+version of iconv.
+
+If you really want to, you can configure Mutt --without-iconv, but
+there will then be no character set conversion.
