title: Initialising a std::string from a character
body: <p>There doesn't seem to be a standard constructor so I've taken to doing the following</p>
  
  <pre><code>void myMethod(char delimiter = ',')
  {
      string delimiterString = 'x';
      delimiterString[0] = delimiter;
      // use string version ...
  }
  </code></pre>
  
  <p>Is there a better way to do this?</p>
