body: <p>Is it possible to add a trademark symbol to project name in Doxygen?</p>
  
  <pre><code>PROJECT_NAME = "Company Product Name(tm)"
  </code></pre>
  
  <p>This appears as the home page title, and it would be very nice to have trademark symbol there.</p>
  
  <p>p.s.
  This does not work:</p>
  
  <pre><code>PROJECT_NAME = "Company Product Name&amp;tm;"
  </code></pre>
