Setpagetitle And Registermetatag Problem

If there is [color="#FF0000"] -[/color] in the title or meta tags content then these functions output empty string

Yii::app()->clientScript->registerMetaTag(‘Dubai Property and UAE Real estate - Find quality properties…’, ‘decription’);

Including - in the content makes the meta tag to show empty string in content, if I remove it then it works ok.

Same goes for setting title
