OK. I give up, then.

IE+MathPlayer gets

      Content-Type: application/xhtml+xml

All XHTML-UA's get

     Content-Type: application/xhtml+xml; charset=UTF-8

HTML-UA's (including IE without MathPlayer) get

     Content-Type: text/html; charset=UTF-8

Instiki pages are  served with a

     <meta http-equiv="Content-Type" content="text/html;  
charset=UTF-8" />

This is ignored by XHTML-UA's. They get the encoding from the HTTP  
headers. (For present purposes, I am avoiding an <?xml?> declaration,  
so as not to have to deal with IE in quirks mode.)

IE+MathPlayer is an HTML-UA masquerading as an XHTML-UA. So it will,  
presumably, get the encoding from the <meta> element.

Hopefully, that will suffice.
