title: binary operator "<<" can't be applied to the expressions of type "wostream" and "string"

    <p>binary operator "&lt;&lt;" can't be applied to the expressions of type "wostream" and "string".</p>

  <p>by CLion's inspector ( my IDE) , whenever my code looks like this.  </p>
  
  <pre><code> stringstream ss;
              ss &lt;&lt; "Foo baré féé bar"
                 &lt;&lt; someObj-&gt;aStdStringProperty &lt;&lt; endl;
  </code></pre>
  
  <p>(accents like "é" on purpose )  </p>
  
  <p>It compiles and links just fine and it's really the string member part that makes it throw an error.  </p>
  
  <p><em>FYI, I'm not the one who has written this, it's on a project I'm working on.</em>   </p>
  
  <p>I'm no used to strings, wostreams, w_char and all that stuff in C++, so I'm a bit confused about whether it's my IDE being too harsh or myself misunderstanding my lessons/readings.</p>
  
  <p>Thanks in advance !</p>
