body: <p>I am working on a desktop application.
  I am facing this problem.</p>

  <p>As you can see in the screenshot when this code runs it assigns Russian string to CString but its value gets corrupted.</p>
  
  <pre><code>CString csField = vField.bstrVal;
  </code></pre>
  
  <p>The bstrVal contains Створное O^Л.
  When I assign it to CString it becomes ??s.</p>
