title: Cyrillic alphabet validation
body: <p>I came across an interesting defect today the issue is I have a deployment of my web application in Russia and the name value "Наталья" is not returning true as alphaNumeric in the method below. Curious for some input on how people would approach a problem like this! - Duncan </p>
  
  <pre><code>private boolean isAlphaNumeric(String str) {
      return str.matches("[\\w-']+");
  }
  </code></pre>
