It looks like tika is asking the XML library to handle chracter 147 ie 0x93
which is not allowed in HTML.
This saxon XML library is not happy with that, I think the default java one
doesn't complain when given the invalid character though, however tika is
probably wrong to write out that character when writing XHTML.
