title: N prefix and parameter
body: <p>I have some stored procedure </p>
  
  <pre><code>CREATE PROC MyProc ( @FullName NVARCHAR(200) = NULL )
      AS --.............
  </code></pre>
  
  <p>When I call this proc as <code>exec MyProc 'Some english text'</code> it works good.</p>
  
  <p>But if call it as <code>exec MyProc 'Русский текст'</code> that is using Russian alphabet, it doesn't work properly. </p>
  
  <p>And the call <code>exec MyProc N'Русский текст'</code> works good again. </p>
  
  <p>I have a client application and... I need to add  N prefix to parameters? If yes, how do I do it?</p>
