[Mailman-Users] character encoding error

[Dan Phillips]

When I updated to 2.1.3 I immediately had problems with Japanese 
language password reminders causing errors, but I applied the patch 
provided by Tokio Kikuchi and those went away. Since then, however, 
every time I receive a post that includes an unusual (for English) 
character -- ç, 1/2 (as one character), anything with an umlaut, etc -- 
the following error message is generated:

object has no attribute 'lower'

Oct 09 08:04:51 2003 (449) SHUNTING: 
1065704690.3426059+c2b29a13c674529127a4c79472d3c58829f5937c
Unfortunately, every message received after the offending one is also 
shunted, and cron/senddigests also produces the same error message. A 
quick look at the digest.mbox shows one character that appears in pico 
as a black diamond with a question mark in it. If I replace that with 
an approximation without a diacritical and save the mbox, then I can 
run /cron/senddigests and unshunt successfully.

Any ideas?
