title: Appending a DegreeSymbol in a string
body: <p>I want to append a degree symbol to the string for example 55.66° so I use 
      <code>
       std::wostringstream stream;
       stream&lt;&lt;"55.66"&lt;&lt;"°";</code></p>
  
  <p>then I convert it into wstring like  stream.str()
  the output I Get is 55.66Â°</p>
  
  <p>An extra A is added.How can I remove that?
  I have also tried with stream&lt;&lt;"55.66"&lt;"\u00B0"</p>
