title: Flex TextInput restrict: Restrict punctuation
body: <p>I have need to restrict user input. TextInput should restrict all special characters and punctuation. Any other characters are allowed. In java there is a regex patter:</p>
  
  <pre><code>replaceAll("\\p{Punct}", "_")
  </code></pre>
  
  <p>Is there something similar in actionscript?</p>
