title: C++ Unrecognized escape sequence
body: <p>I want to create a string that contains all possible special chars.</p>
  <p>However, the compiler gives me the warning <em>&quot;Unrecognized escape sequence&quot;</em> in this line:</p>
  <pre><code>wstring s=L&quot;.,;*:-_⁊#‘⁂‡…–«»¤¤¡=„+-¶~´:№\¯/?‽!¡-¢–”¥—†¿»¤{}«[-]()·^°$§%&amp;«|⸗&lt;´&gt;²³£­€™℗@©®~µ´`'&quot; + wstring(1,34);
  </code></pre>
  <p>Can anybody please tell me which one of the characters I may not add to this string the way I did?</p>
