title: Javascript regex to accept only letters, spaces, and ñ
body: <p>I am looking for a Javascript regex to make sure the string contains only spaces, letters, and ñ — case insensitively.</p>
  
  <p>I already tried: <code>/^[A-Za-z _]*[A-Za-z][A-Za-z _]*$/</code> but it fails to accept <code>ñ</code>.</p>
