UnicodeEncodeError on wiki and ticket notifications containing non-ascii codes

[anonymous]

If I choose diff for wiki pages, and if there is a non ascii in the diff itself, exception is thrown, visible only in trac log:

    self._do_send(transport, event, k, v, fmtdict[k])
  File "build/bdist.linux-armv5tel/egg/announcer/distributors/mail.py", line 481, in _do_send
    msgText = MIMEText(alternate_output, alt_msg_format)
  File "/usr/lib/python2.7/email/mime/text.py", line 30, in __init__
    self.set_payload(_text, _charset)
  File "/usr/lib/python2.7/email/message.py", line 226, in set_payload
    self.set_charset(charset)
  File "/usr/lib/python2.7/email/message.py", line 262, in set_charset
    self._payload = self._payload.encode(charset.output_charset)
UnicodeEncodeError: 'ascii' codec can't encode character u'\u0161' in position 259: ordinal not in range(128)

I have traced problem down to announcer/distributors/mail.py. Following patch fixes problem for me:

I am running python 2.7.5
