title: AS3 - RegExp with special characters
body: <p>I'm trying to find all words with a hash in front if they are placed after the end of the sentence. 
  (These ones: <strong>#Example #FOO #hello_world #foo-bar #2012 #special-äüöå #russia-Русский #arabic-العربية</strong>) </p>
  
  <p>This is the RegExp:</p>
  
  <pre><code>var regex:RegExp = /#[\w\-]+?(?= #|$)/g;
  </code></pre>
  
  <p>This is the text:</p>
  
  <blockquote>
    <p>Lorem ipsum dolor #sit_amet, consetetur sadipscing, sed #diamnonumy
    eirmod tempor #invidunt ut. 
     #Example #FOO #hello_world #foo-bar #2012 #special-äüöå #russia-Русский #arabic-العربية</p>
  </blockquote>
  
  <p>It works except if special characters are included such as in <strong>#special-äüöå #russia-Русский #arabic-العربية</strong></p>
  
  <p>How to extend the RegExp to recognize special characters and non latin languages?</p>
  
  <p>Thanks. Uli</p>
