title: QFile doesn't recognize file:/// url path format
body: <p>I get the file path from Qml like this:</p>
  
  <pre><code>mainView.projectFilePath = Qt.resolvedUrl(newProjectFileDlg.fileUrl).toString();
  </code></pre>
  
  <p>The above file path looks like this: file:///C:/uuuu.a3</p>
  
  <p>But when this path is passed to QFile, it complains </p>
  
  <pre><code>The filename, directory name, or volume label syntax is incorrect
  </code></pre>
  
  <p>How to solve this problem?</p>
