Neither do I, nor can I reproduce the problem at the moment.  But here are 
some things to look into that I noticed when grabbing the above URL with wget 
and libwww-perl's HEAD tool:

- No charset parameter in HTTP Content-Type header
- XHTML 1.1 served as text/html
- No XML declaration (IIRC this means XML processors will default to UTF-8)
- The document contents are ISO-8859-1

Unlike the markup validator, plain XML parsers quite likely will not do 
anything with the charset in the document's meta http-equiv tag.
