title: JSON specifies "any UNICODE character"?
body: <p>Maybe this is just my unfamiliarity with unicode, so please correct me if I'm mistaken.</p>
  
  <p>Looking at <a href="http://json.org/" rel="noreferrer">http://json.org/</a>, the spec says that a string can include "any UNICODE character", but this confuses me.</p>
  
  <ul>
  <li>JSON is a communication format
  correct? At the core of it,
  everything must translate down to
  bytes. </li>
  <li>In contrast, UNICODE is a
  logical format and must be encoded to
  be able to transmit it, right?</li>
  </ul>
  
  <p>So what did they mean there?</p>
