ContentRules, Mail Notification - encoding error

[Luis Miguel Braga]

Hi,

when I was trying to use a content rule to send emails notifications on
workflow state changes I got an encoding error.

......
Module plone.app.contentrules.handlers, line 97, in execute
Module plone.contentrules.engine.executor, line 27, in __call__
Module plone.contentrules.rule.rule, line 48, in __call__
Module plone.app.contentrules.actions.mail, line 94, in __call__
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1:
ordinal not in range(128)


It only happened when the title of the object had special characters.
For example:
If the title was "Pós-Graduado" I'd get the error.
If I changed the title to "Pos-Graduado", the notification would work fine.

I when messing around  in plone.app.contentrules and fixed the problem
by replacing
        event_title = obj.Title()
with
        event_title = obj.Title().decode('utf-8')


I'm not sure that this is the correct way to address this issue.
What do you guys suggest?

For a long time I've systematically defined Python's default encoding to
be 'utf-8' in machines running Plone, to prevent such issues.   In
Debian Etch systems, I simply edit the definition of setencoding () in
/etc/python2.4/site.py, making
   encoding = "utf-8"
(used a few lines down, in the same function, in a call to
sys,setdefaultencoding () ).

Right now I can't remember if default-zpublisher-encoding,
from the zope.conf file, would also have some effect there (although I
also set it to 'utf-8'...).

Best regards
