Not all valid UTF-8 is valid in XML.  Only a subset, as defined in
http://www.w3.org/TR/2008/REC-xml-20081126/#charsets

Note that Form Feed (0xC) is not allowed.  Your original input document 
contains a formfeed character, and this is what ends up being invalid.  
It's not a matter of escaping; form feed as a literal byte, numeric 
reference, etc., is not allowed.
Stripping the form feed from the input allows it to serialize properly.
