title: clang++ and u16string
body: <p>I'm having a hell of a time with this simple line of code and the latest clang++</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  #include &lt;string&gt;
  
  using std::u16string;
  
  
  int main ( int argc, char** argv )
  {
      u16string s16 = u"鵝滿是快烙滴好耳痛";
  
      return EXIT_SUCCESS;
  }
  
  
  Ben-iMac:Desktop Ben$ clang++ -std=c++0x -stdlib=libc++ main.cpp -o main
  main.cpp:15:21: error: use of undeclared identifier 'u'
      u16string s16 = u"鵝滿是快烙滴好耳痛"
  </code></pre>
