This module contains an interface to the iconv library functions. The iconv library functions convert strings between various character sets encodings. The supported character sets depend on the iconv() implementation on your system. Note that the iconv() function on some systems may not work as well as you expect. In this case, you should install the libiconv library.
Your systems standard C library must provide the iconv() function or you must have libiconv installed on your system. The libiconv library is available from http://www.gnu.org/software/libiconv/.
To be able to use the functions defined in this module you must compile your PHP interpreter using the configure line --with-iconv[=DIR].
The behaviour of these functions is affected by settings in php.ini.
