title: Regex for minimum number of characters
body: <p>I created this regular expression to validate names:</p>
  <pre class="lang-none prettyprint-override"><code>^[a-zA-Z0-9\s\-\,]+.\*?$
  </code></pre>
  <p>Is there a way add the minimum number of characters?</p>
  <p>I know we can use <code>{x,}</code>, but I cannot make it work.</p>
