[Mailman-Users] Corrupt subscribers file

[Con Wieland]

After upgrading I have lists that now have invalid addresses, for 
example:

mb at poisson@usc.edu
Also some have ? marks at the end also causing problems
When running:

https://maillists.uci.edu/mailman/admin/soe-enewsletter/members

I get the following error:

Traceback (most recent call last):
   File "/usr/local/mailman/scripts/driver", line 87, in run_main
     main()
   File "/usr/local/mailman/Mailman/Cgi/admin.py", line 198, in main
     show_results(mlist, doc, category, subcat, cgidata)
   File "/usr/local/mailman/Mailman/Cgi/admin.py", line 501, in 
show_results
     form.AddItem(membership_options(mlist, subcat, cgidata, doc, form))
   File "/usr/local/mailman/Mailman/Cgi/admin.py", line 873, in 
membership_options
     all = [_m.encode() for _m in mlist.getMembers()]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xa0 in position 
22: ordinal not in range(128)

The list works otherwise and folks can continue to subscribe and 
unsubscribe. The only way I have found to remedy this is to remove the 
list and add it back. Does anyone have any ideas on an easier way to 
recover?
