title: Escape string for javascript: hex in json
body: <p>This string </p>
  
  <blockquote>
    <p>{\x22Address\x22:\x22some address with quotes \x22}</p>
  </blockquote>
  
  <p>is parsed by JSON.parse correctly in browser. Why? What do hex numbers mean in json string? I can't find explanation.</p>
