Hi, Kawada san,
The problem is that the Japanese mail users/MUA developers use CP-932
charset as Shift-JIS and its derivatives (ISO-2022-JP/EUC-JP). CP-932
contains more (extended) characters than Shift-JIS while Python codec is
strict on the latter. The characters like circled numbers fail to be
decoded in unicode and cause error.
Similar errors are reported in Japanese Mailman users, like the thread
A workaround is to patch charset.py in Python email library as:
--- Lib/email/charset.py 2009-09-22 08:59:56.000000000 +0900
+++ Lib/email/charset.py.orig 2009-09-22 08:58:36.000000000 +0900
