Strange Browser Behavior

Recently I found my browser (Firefox 2 Mac) converting a numerical
character reference outside the Unicode code space into a sequence of
Unicode codepoints, instead of simply "not defined." I would be
grateful if anyone could tell me whether the Win Mozilla/Firefox or IE
7 browsers do this too. A test page is here:

It looks to me like the sequence being produced in this particular case
is actually FEFF E083 DDBD. If anyone has an idea about what kind of
process could translate � into that sequence or its UTF-8 or
binary equivalent, I'd be interested to hear it.
