title: Regex-expression with danish characters
body: <p>I'm currently trying to wrap my head around regex, I have a validation snippet that tests an input box against a regex-expression:</p>
  
  <pre><code>$.validator.addMethod("customerName", function(value, element){
  return (/^[a-zA-Z]*$/).test(value);
  }, "Some text");
  </code></pre>
  
  <p>That works well, but when I try to add a space and some special danish characters, it doesn't filter the danish characters, only the space.</p>
  
  <pre><code>$.validator.addMethod("customerName", function(value, element){
  return (/^[a-zA-Z æøåÆØÅ]*$/).test(value);
  }, "Some text");
  </code></pre>
  
  <p>Any ideas to what could be wrong?</p>
