title: assigning a very big hexadecimal to a char through \u or \x
body: <pre><code>char k = '\u103BD';
  </code></pre>
  <p>I get a <strong>compile time error</strong>.<br>
  I want to put the following char in my char <code>k</code> but it seems that the escape sequence will not accept more than <code>4</code> digits.<br>
  What should I do in this case?
