title: C++ inserting wchar_t backslash into string
body: <p>I have a wide char literal:</p>
  
  <pre><code>const wchar_t* charSet =  L" !\"#$%&amp;'()*+,-./0123456789:;&lt;=&gt;?\n"
                                  L"@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_\n"
                             L"`abcdefghijklmnopqrstuvwxyz{|}~\n";
  </code></pre>
  
  <p>When I pass it into text processor '\'(backslash) isn't there.Now if I put instead \\ it</p>
  
  <p>I am getting compile time error: </p>
  
  <blockquote>
    <p>"missing closing quote"</p>
  </blockquote>
  
  <p>So how do I put backslash into such a char string?</p>
