plane 1 characters in Internet Explorer

As described in 
http://www.w3.org/Math/characters
the XML parser used in Internet Explorer 6 fails to accept characters
above the basic plane of unicode, that is with unicode numbers greater
than hex FFFF. This has the effect that IE6 will reject every document
that refers to the MathML DTD as the DTD uses references to these
characters to define entities for the math alphabetic chgaracters, Afr
etc.

I'm pleased to report that Microsoft have released a new version
"Internet Exploer 6 SP1"
which cures this problem. This is available as a free download from
Microsoft's site at
http://www.microsoft.com/windows/ie/downloads/critical/ie6sp1/default.asp


I have no connection with Microsoft, but have installed this update on my
machines and can confirm that this new release does parse the MathML
DTD. I recommend this update to any users of Internet Explorer who are
interested in MathML.


David
