title: How to convert actual Unicode to \u0123
body: <p>I want to turn Unicode text into pure ASCII encoding using escape sequences.</p>
  <p>Input :<code>Ɏɇ衳</code> outputs to ... <code>&quot;\u024E\u0247\u8873&quot;</code></p>
  <p>Basically the <strong>opposite</strong> of this.</p>
  <pre><code>$ echo -e &quot;\u024E\u0247\u8873&quot;
  Ɏɇ衳
  </code></pre>
  <p>I want the encoding to stay in <code>utf8</code>, all I'm doing is changing forms.</p>
  <h3>I've Tried:</h3>
  <pre><code>iconv -f utf8 -t utf8  $file
  iconv -f utf8 -t utf16  $file
  </code></pre>
