title: Decimal to Unicode Char in C++
body: <p>How do I convert a decimal number, 225 for example, to its corresponding Unicode character when it's being output? I can convert ASCII characters from decimal to the character like this:</p>
  
  <pre><code>int a = 97;
  char b = a;
  cout &lt;&lt; b &lt;&lt; endl;
  </code></pre>
  
  <p>And it output the letter "a", but it just outputs a question mark when I use the number 225, or any non-ascii character.</p>
