Joomla Module. What is this =>�

[Mojtabarahimi]

Hi guys
I used the joomla cms for web development.
Actually i install the roknewsrotator module and use it for Persian language that it decode with UTF-8.
i don't know why the News rotators module want to show some news in UTF-8 language, at the end of the sentences it showed this icon : �
i try to fix it, but until now, i was unsuccessful.
I find all of php file of this module and change all of them from ANSI to UTF-8.
But the problem persist.
If anyone can help me, please guide me.
Thank you

Check the collation and charset of your mysql table. Try utf-8 and utf_unicode_ci

Thank you ardav

I tried that, but unfortunately same problem.

here in the module code, do you think that there is something incorrect in that?!
Look at the line 10 to 14.
I think something is wrong in there.

defined('_JEXEC') or die('Restricted access');

require_once (JPATH_SITE.DS.'components'.DS.'com_content'.DS.'helpers'.DS.'route.php');
jimport('joomla.utilities.date');

class modRokNewsRotatorHelper
{
	function prepareContent( $text, $length=300 ) {
		// strips tags won't remove the actual jscript
		$text = preg_replace( "'<script[^>]*>.*?</script>'si", "", $text );
		$text = preg_replace( '/{.+?}/', '', $text);
		// replace line breaking tags with whitespace
		$text = preg_replace( "'<(br[^/>]*?/|hr[^/>]*?/|/(div|h[1-6]|li|p|td))>'si", ' ', $text );
		$text = strip_tags( $text );
		if (strlen($text) > $length) $text = substr($text, 0, $length) . "...";
		return $text;
	}	
	
	function getRotatorImage($text) {
        $regex = "#<!--IMAGE\s(.*?)IMAGE-->#s";
        preg_match( $regex, $text, $matches );
        if (sizeof($matches)==2) return trim($matches[1]);
        else return false;
    }
	
	function getList(&$params)
	{

    		}
    	}

		// Content Items only
		$query = 'SELECT a.*, ' .
			' CASE WHEN CHAR_LENGTH(a.alias) THEN CONCAT_WS(":", a.id, a.alias) ELSE a.id END as slug,'.

		$db->setQuery($query, 0, $count);
		$rows = $db->loadObjectList();

		$i		= 0;
		$lists	= array();
		foreach ( $rows as $row )
		{
		    $lists[$i]->mainimage = modRokNewsRotatorHelper::getRotatorImage($row->introtext);
			$lists[$i]->link = ContentHelperRoute::getArticleRoute($row->slug, $row->catslug, $row->sectionid);
			$lists[$i]->title = htmlspecialchars( $row->title );
			$lists[$i]->introtext = modRokNewsRotatorHelper::prepareContent($row->introtext, $params->get('preview_count', 300));
			$lists[$i]->date = new JDate( $row->created );
			$i++;
		}

		return $lists;
	}



}

There's nothing there that I can see. Put this at the top of the page:

header('Content-Type: text/html; charset=utf-8');

If that doesn't work, there's a bit of code I sometimes use for stubborn encoding problems:

mysql_query('SET names=utf8');
	mysql_query('SET character_set_client=utf8');
	mysql_query('SET character_set_connection=utf8');
	mysql_query('SET character_set_results=utf8');
	mysql_query('SET collation_connection=utf8_unicode_ci');

Thank you ardav for your reply.
I do that, but the problem persist! :(
i don't know why! it is the first time that i have dealing with this problem.
You can see the website with this link : http://www.ikgsch.com
Pay attention to central slider, some slides doesn't have any problem and some of them have got problem.

I found some java script file in the module folder.
Have a see :

Had a look - seems to be the character before the '...' in some slides. Is it the same character every time?

[Mojtabarahimi]

yes, i checked each slides exactly.
All of them are same.
i think there is a problem in coding and php source.
:(

Just thought, it could be because you have Persian chars and substr is chopping them incorrectly - in the middle of the character:

if (strlen($text) > $length) $text = substr($text, 0, $length) . "...";

Try using mb_* string function equivalents with Persian:

http://php.net/manual/en/function.mb-substr.php

Persian uses multi-byte characters (I think).

if (mb_strlen($text,'UTF-8') > $length) $text = mb_substr($text, 0, $length, 'UTF-8') . "...";

Hope that works :)

[Mojtabarahimi]

WoooooooooooooooooooooooW!!!!
You are great man!!! very very great!
I don't know how can i say thank you to you.
