title: StringEscapeUtils.escapeXml is converting utf8 characters which it should not
body: <p><code>escapeXml</code> function is converting <code>ѭ Ѯ</code> to <code>&amp;amp;#1133; &amp;amp;#1134;</code> which I guess it should not. What I read is that it Supports only the five basic XML entities (<code>gt</code>, <code>lt</code>, <code>quot</code>, <code>amp</code>, <code>apos</code>).</p>
  <p>Is there a function that only converts these five basic xml entities?</p>
