AnnouncerPlugin failure

[Roger.Ob...@gmail.com]

Yesterday my Announcer Plugin decided to complain about a non-ASCII character
in a message:

2013-11-07 14:34:04,788 Trac[api] ERROR: AnnouncementSystem failed.
Traceback (most recent call last):

self._payload = self._payload.encode(charset.output_charset)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in position
472: ordinal not in range(128)

I now get this for all messages. The position of the character changes, but
the character remains u'\xf6'

I am not aware of any change to the system. I haven't a clue where to look.
Any pointers?

Sounds similar to http://trac-hacks.org/ticket/10974

The suggested fix seemed to get my mail messages started again.

The mystery is why this showed up out of the blue. I have not modified the
Trac install. The messages that failed did not contain non-ASCII characters.
Very odd.

Hmm. The fix seemed to work for a while. I have not updated any part of Trac.
However, I once again no longer get e-mail announcements, and the Trac log
complains with:

Why would the error go away and then come back?

Are you sure the messages that fail don't contain any '�' (u'\xf6')
characters?

Did you use the entire patch from comment 2?
It seems that line would be changed different:
msgText = MIMEText(alternate_output, alt_msg_format, self._charset)

(Although I would be more confident in the fix suggested in comment 9.)

Of course some messages may contain ööåÖÖÅ and maybe others. They have always
done so. That is no change in usage. What is different is that, perhaps
depending on the phase of the moon, these messages are no longer accepted by
the Announcer plugin.

I did the workaround in comment 7 for Trac 1.0.1. To be honest, the various
lists of possible fixes was unclear to me. Some were suggestions that may not
have solved the issue. Some were offered out of context and did not tell where
the fix was to be applied. So I did a conservative change. I am willing to try
something else.
