for urgent solution to meet my need I make a read more with very simple php code strip_tags and substr

$desc = strip_tags(substr($data->description, 0, 200))."....";        
echo $desc;
echo CHtml::link('read more', array('view', 'id'=>$data->id),array('class'=>'btn btn-success btn-small'));

workaround

I manage to use this the "old fashion" way by using this code instead

$string = $data->content;
if(mb_strlen($string, 'utf-8') >= 700){
       $string = mb_substr($string, 0, 700 - 5, 'utf-8')." ".CHtml::link(CHtml::encode("read more..."), $data->url);
}
echo $string;

utf works ok and there's no need to use extensions. But still there's the problem with the cuts inside some tags like "ul". But it works.

Utf problem

For this to work for a certain number of chars I'm using this, but still can't work around utf, any ideas?

if (strlen($data->content)<500) {
                              echo $data->content;
                            }
                            else
                            if (strlen($data->content)>500) {
                                $this->beginWidget('application.extensions.ereadmore.EReadMore', array('linkUrl'=>$data->url));
                                echo $data->content;
                                $this->endWidget();
                            }
                            else {
                              echo $data->content;
                            }                            
                            //echo $data->content;
                            $this->endWidget();

Utf characters

After a few more tests i found out that this is actually working.

$this->beginWidget('application.extensions.ereadmore.EReadMore', array('linkUrl'=>$data->url));
    echo $data->content;
    $this->endWidget();

but the utf characters are not properly shown. Any ideas?
