Comment:

 In regards to the original reporter's case:
 http://core.trac.wordpress.org/ticket/5998#comment:9

 It could be strongly argued (http://www.webdevout.net/articles/beware-of-
 xhtml) that it is not a good idea to turn on "true XHTML serving in
 WordPress" but if this is a valid request, it makes sense to resolve it.

 This case is specific to XHTML/XML and UTF-8 and the fact that Firefox
 (for example) will 'choke' on non valid code points. (example 
 )

 It makes sense to me, that since this related to XHTML/XML, handle it as
 such.

 (although, is it acceptable to assume that the php xml parser will be
 avail in standard Wordpress/php setups?)

 I am including a patch. (for comment's only, as that is what is specified
 in the original report)

 btw: text/html mode is not effected by this issue. (current input
 filtering handles it)
