A related issue is that the charset in that HTML part is reported to  
be "unicode".  This is not a valid charset (see  
http://www.iana.org/assignments/character-sets).  I can only guess  
that libxml does some kind of best-guess as to the current charset if  
given bad charset input - it's possible on your system that this best  
guess is ISO-8859-1, while on my system it is UTF-8, which would  
explain why it works on some systems but not others.  (You can test  
and see if this is the case by changing the 'unicode' charset  
definition in the HTML part to 'UTF-8').

However, there is nothing we can do if this is the case.  We can't  
change the charset contained within HTML code because we have to parse  
the HTML first (via the xml functions) - but this parsing code will  
apply the charset found in a meta charset tag during the parsing itself.
