I am hoping that you can upgrade Moin in this way, not having looked at Moin 
with pip for a long time, if ever.

Do you know what it is trying to read here? Maybe there is a list of 
configuration files in the setup.py script or setup.cfg.

It looks like ConfigParser has been given a file object by distutils that has 
been opened by something like codecs.open. That isn't a problem - it is how I 
open files in Python 2 and read Unicode out of them - but it seems as if 
something expects UTF-8 and the file contains something else.
