This module contains an interface to the GNU Recode library,
version 3.5. To be able to use the functions defined in this
module you must compile you PHP interpreter using the --with-recode
option. In order to do so, you must have GNU Recode 3.5 or higher
installed on your system.
</para>
<para>
The GNU Recode library converts files between various coded
character sets and surface encodings. When this cannot be
achieved exactly, it may get rid of the offending characters or
fall back on approximations. The library recognises or produces
nearly 150 different character sets and is able to convert files
between almost any pair. Most RFC 1345 character sets are supported.

<para>
Crashes and startup problems of <literal>PHP</literal> may be encountered
when loading the recode as extension <emphasis
role="strong">after</emphasis> loading any extension of <link
linkend="ref.mysql">mysql</link> or <link
linkend="ref.imap">imap</link>. Loading the recode before those
extension has proven to fix the problem. This is due a technical problem
that both the c-client library used by imap and recode have their own
<literal>hash_lookup()</literal> function and both mysql and recode have
their own <literal>hash_insert</literal> function.
