Hi,

Character Encoding is currently detected erroneously when the document uses SGML SHORTTAG constructs. The following document is valid SGML document and parses without errors (using SP 1.3.4):

  <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0 Strict//EN"><TITLE/test document/<META http-equiv=Content-Type content="text/html;charset=ISO-8859-1"<P>

However, the W3C Validator fails to read the character encoding information from the META element and issues a warning. The following document is the same document, but with the SHORTTAG construct not used in the META element.

  <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0 Strict//EN"><TITLE/test document/<META http-equiv=Content-Type content="text/html;charset=ISO-8859-1"><P>

This passes the validation without warnings. Both documents have the exact same parse tree:

    AVERSION CDATA -//IETF//DTD HTML 2.0 Strict//EN
  <HTML>
    <HEAD>
      <TITLE>
         test document
      </TITLE>
        AHTTP-EQUIV TOKEN CONTENT-TYPE
        ACONTENT CDATA text/html;charset=ISO-8859-1
      <META>
      </META>
    </HEAD>
    <BODY>
      <P>
      </P>
    </BODY>
  </HTML>
  C

Cheers,

Jarno
