list_members --fullnames kills umlauts in names

This is not a bug in list_members. list_members encodes the full names for output in the default encoding of the Python installation. If you want this to be, e.g., iso-8859-1 or utf-8 as opposed to ascii which is the normal Python default, you have to add, e.g., sys.setdefaultencoding('utf-8') to a sitecustomize.py module. See <http://docs.python.org/library/sys.html#sys.setdefaultencoding>.

For example, if you want utf-8 encoding as the Python default, you could create /usr/lib/pythonv.v/site-packages/sitecustomize.py containing the two lines:

import sys
sys.setdefaultencoding('utf-8')

Thanks, that worked!

Nice-to-have would be if list_members used the LANG setting (f.x. I have LANG=de_DE.UTF-8) to determine the output encoding to use.

This is really still a Python request, but I changed it back to New->Wishlist per comment #2.
