title: Special characters (^´`) do not invoke (keyPressed / keyReleased / keyTyped) method of TextField
body: <p>I have a <code>javafx.scene.control.TextField</code> and implemented the <code>keyPressed()</code>, <code>keyReleased()</code>, and <code>keyTyped()</code> methods.</p>
  
  <p>These methods will be invoked by all keys except for ^ ´ `. </p>
  
  <p>The problem is that the <code>TextField</code> adds these characters but I can't handle the input of these characters.</p>
  
  <p>I think it's because these characters are no "real" characters and they are normally used in combination with vocals (like é, ì, ô, ú). But even when I "complete" the character (e.g. if I press ^ and then o, then the <code>TextField</code>will show ô), the methods does not register the input.</p>
