default_export_charset error when exporting

[johnmd]

Hello
I am running 3.5.1a on Apache/2.2.3,with PHP 5.2.2 (cli) (built: Oct 15 2007 16:22:11),I am having a difficulty with exporting and importing contacts.I am getting the following error.

<b>Warning</b>: mb_convert_encoding() [<a href='function.mb-convert-encoding'>function.mb-convert-encoding</a>]: Unknown encoding &quot;0&quot; in <b>/var/www/html/crm/include/Localization/Localization.php</b> on line <b>308</b><br />

in php.ini the default_charset = "ISO-8859-1"

in Localization.php the settings are
var $default_export_charset = 'ISO-8859-1'; // not camel hump to match sugar_config's
var $default_email_charset = 'ISO-8859-1';

However when I try to export I am still getting the same error.I know this is something simple,but having searched the fourms,Icannot seem to find an answer to the same,additionally I note that further down in the Localization.php,there are mentions of UTF-8.

$strings[$k] = $this->translateCharset($v, 'UTF-8', $charset);
return $this->translateCharset($var, 'UTF-8', $this->getOutboundEmailCharset());
$bean->$k = $this->translateCharset($bean->$k, 'UTF-8', $this->getExportCharset());
* @param string toCharset the charset to translate into (defaults to UTF-8)
function translateCharset($string, $fromCharset, $toCharset='UTF-8') {
function translateCharsetMIME($string, $fromCharset, $toCharset='UTF-8', $encoding="Q") {

I am not sure if I need to, or should change these as the actual Database_Collation is set for utf8_general_ci
under the web front end/Localization settings screen.
Any help wpuld be greatly appreciated.


Also trying to install Zucar reports and some other modules also seems to fail?
Thanks
