title: Regex for Umlaut
body: <p>I am using JS Animated Contact Form with this line of validation regex:</p>
  
  <pre><code>rx:{".name":{rx:/^[a-zA-Z'][a-zA-Z-' ]+[a-zA-Z']?$/,target:'input'}, other fields...
  </code></pre>
  
  <p>I just found out, that I can't enter name like "Müller". The regex will not accept this. What do I have to do, to allow also Umlauts?</p>
