Thanks for your help.  I thought it was an encoding problem too.  I'm using 
python 2.6.2.  

How do I find out the encoding of the web page?  Doesn't appear to be in the 
source.  The other problem I have, is that I'm not sure how to fix the 
encoding once I've worked it out what the encoding of the web page is.  I'm a 
bit of a newb, and am not sure exactly how this encoding thing works.
