title: JSON.stringify() to UTF-8
body: <p>Javascript uses as far as I know UTF-16 fundamentally as a standard for strings. With JSON.stringify() I can create a JSON string from an object.</p>
  
  <p><strong>Is that JSON string UTF-16 encoded?</strong></p>
  
  <p><strong>Can I convert (hopefully fast) that string to UTF-8 to save bandwidth for huge files (1MB JSON)?</strong></p>
