title: Flutter: unwanted ellipsis in scaffold Actionbar title , Persian word
body: <p>I set title of <code>Actionbar</code> in Scaffold a Persian word :  </p>
  
  <pre><code>new Scaffold(
        appBar: new AppBar(
          title: new Text('لغت نامه'),
          centerTitle: true,
          actions: &lt;Widget&gt;[
            new Icon(Icons.settings)
          ],

  <p>I don't have any idea why this is happening. How can I prevent this?</p>
  
  <p>this Persian title has 8 alphabet, if I set the title in English with the same size, no problem occurs, the problem is with Persian alphabet.  </p>
  
  <p><strong>Workaround</strong><br>
  I put 3 space before and after the Persian text: '\u0020\u0020\u0020لغت نامه\u0020\u0020\u0020'  </p>
