The xml.dom.ext PrettyPrint can only handle 7-bit ASCII or Unicode 
encoded text node strings.  Method1 will fail as your latin1 encoded 
string contains 8-bit values which are not valid utf-8 encodings, as the 
error message reports.  Method2 is in fact working - the output you see 
is the utf-8 encoding for your text node string.  If you look at the 
output generated in a Unicode editor you should see your original string.

The xml.dom.ext PrettyPrint can only produce utf-8 output.  There is a 
bug report and patch on sourceforge to let it produce utf-16 output.
