I wasn't even aware there are two camps. What would be the reasons not 
to use setdefaultencoding? As I configured it now it uses the systems 
locale to set the encoding. I'm using the same machine to retrieve data, 
  manipulate it and store in a database (on the same machine).
I would like to understand what could be wrong in this case.

What I mean is that I encode the data when I store it in the DB and 
decode it when I retrieve the data from the DB. I do this because 
SQLObject doesn't support the binary data. As long as the result that 
comes back out is exactly the same as it was when it went in, I don't care.

I'm just doing it the easy way, I guess. I get the data from the win32 
call as Unicode data, even when it contains binary data. Perhaps that I 
will transform this data in a later phase to more usefull format, but 
that'll depend on the need.

This is really not my thing. I noticed that on my system the encoding is 
now set to cp1252. What would be the difference if I switched to utf-16-le?

Thanks for your explanation.
