title: Get size of a std::string's string in bytes
body: <p>I would like to get the bytes a <code>std::string</code>'s string occupies in memory, not the number of characters. The string contains a multibyte string. Would <code>std::string::size()</code> do this for me?</p>
  
  <p>EDIT: Also, does <code>size()</code> also include the terminating <code>NULL</code>?</p>
