title: Copy from char16_t* to char16_t*
body: <p>I'm trying to copy a <code>char16_t*</code> that's passed into a function but haven't found any way to do that.</p>
  
  <pre><code>foo(char16_t* characters) {
      char16_t* copiedCharacters;
      //copy characters to copiedCharacters
  }
  </code></pre>
  
  <p>I tried to use <code>strncopy()</code> but it only copies <code>char*</code>.</p>
