1. Filter

   1. widget_text (for the text)
   2. widget_title (for the title)

   Example

   function add_smiley($content) {
   $new_content = '';
   $new_content.= $content . ':)';
   return $new_content;
   }   
   add_filter('widget_text', 'add_smiley');
   

   Note that this works only for the content so not if you have a widget with only a title.

2. You should be able to run a filter on widget_text. The text widget is the only one that calls the widget_text hook.

   http://core.trac.wordpress.org/browser/tags/3.0.1/wp-includes/default-widgets.php

   Line 380 ..

   $text = apply_filters( 'widget_text', $instance['text'], $instance );
   

   So in short, Yes! Would be the direct answer to your question. Hope that helps… 🙂
