[Mailman-Users] Encoding problems

Some of my subscribers have accents and similar in their name and I
had to do the following post install to have Mailman properly work
with these:

## CLI

In order to get list_members -f «list» to properly output non-ASCII
user names I had to put the following:

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

Into /etc/python2.5/sitecustomize.py. This is despite proper setup
of LC_CTYPE on the system. Seems to me Mailman should use the
encoding of the current locale, not this site-wide Python default
encoding (settable by root only).

## Web

For the web page forms to accept non-ASCII I had to put this:

 add_language('en', 'English', 'utf-8')

Into /etc/mailman/mm_cfg.py. I think utf-8 should be the default
because even on an English list, you can use non-ASCII punctuation,
glyphs, and many European subscribers will have non-ASCII in their
names.

## Mailing List

The mailing list letters are correct _except_ that the body now
contains this:

 Content-Type: text/plain; charset="utf-8"
 Content-Transfer-Encoding: base64

And yes, each letter sent to the list is converted into base64.

I tried disabling the above utf-8 changes, but it did not seem to fix
it. But it might be that the list language (containing utf-8) was
copied at list creation time, so I will effectively have to recreate
the list (or write Python code) to change this?

Using Mailman 2.1.9 (Ubuntu installation).
