When the correct mime type is used with Firefox, such as text/xml,
then it does parse the file using an XML parser and it does indeed
drop the #150 - so Firefox behaves as expected.  It seems whenever an
HTML parser is used, it's perfectly ok to use C1 control characters
and expect them to be read using Windows 1252 numbers, regardless of
the charset used.
