nbsp; and other common entities do not validate as HTML5!

The only built-in entities in XML are &, <, >, " and ' XHTML added the others via a DTD that is not a part of HTML5. As such, validators will report them as errors.

Safe replacements are the decimal notation: &#160; or the character itself U+00A0;

Quite a few other common symbols are not available without similar changes.

  • &lt; = &#60;
  • &gt; = &#62;
  • &amp; = &#38;
  • &apos; = &#39;
  • &quot; = &#34;
  • &nbsp;&#160;
  • &copy; = &#169;
  • &reg; = &#174;
  • &trade; = &#8482;
