Sounds a bit like you want to eat your cake and keep it too :-)

As I've said in a previous mail, a CDATA section (which doesn't exist in HTML 
so XMLC can recycle it for that purpose) in the DOM  tells the XMLC HTML 
renderer to output that particular DOM node as is, without applying the usual 
automatic escapes. On the one hand, this means that "<" and ">" aren't 
escaped to "&lt;" and "&gt;", which allows you to put markup in a CDATA 
section. On the other hand, it means that characters that can't be displayed 
in the character set used for output aren't escaped to the corresponding HTML 
entities.

To get it working nonetheless, you've got three (well, two realistic and one 
that's probably not going to work :-) options:

- Don't use allowMarkupInText(true), but instead parse your markup snippets 
into small DOM trees and insert those into the page
- Escape the offending characters by hand. org.enhydra.xml.io.HTMLEntities 
provides a couple of convenience methods for converting characters to named 
entities, and you can get the code for converting characters to numeric 
entities from org.enhydra.xml.io.HTMLFormatter.writeCharacter().
- Make sure all browsers accessing your application accept UTF-8 as transport 
encoding (most modern browsers do, but must be configured to do so), and tell 
Barracuda to use UTF-8 for sending HTML pages.

Hope this helps,

Richard
