title: Special characters in Flutter
body: <p>How can I add a special character (e.g., copyright sign instead of (c)) in the following example:</p>
  <pre><code>Widget copyrightText = new Container(
    padding: const EdgeInsets.only(left: 32.0, right: 32.0),
    child: Text('2018 (c) Author's Name'),
  );
  </code></pre>
