This module contains an interface to the GNU Recode library. 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

You must have GNU Recode 3.5 or higher installed on your system.
You can download the package from http://directory.fsf.org/All_GNU_Packages/recode.html.

strings under certain circumstances. Thus it's safer to use Recode v3.5
or one of the available alternatives like the
To be able to use the functions defined in this
module you must compile your PHP interpreter using the
Crashes and startup problems of PHP may be encountered
when loading the recode as extension after loading any extension of mysql or imap. Loading the recode before those
extension has proved to fix the problem. This is due a technical problem
that both the c-client library used by imap and recode have their own
hash_lookup() function and both mysql and recode have
their own hash_insert function.
