Subject: [CalendarServer-users] Codec error while scheduling events
Message-ID: <971786ea-13d6-c943-c629-ac8f20c62db4@gmail.com>

Hi all,

I'm running calendar/contacts server for about half a year using the 
debian testing version (9.2+dfsg-1).

Sometimes I get the following error:

[txdav.caldav.datastore.scheduling.implicit#error] Unable to format 
event {'log_level': <LogLevel=error>, 'log_source': None, 'log_format':
u'single-organizer: Only one ORGANIZER is allowed in an iCalendar 
object:\n{calendar}', 'calendar': <Component: 'BEGIN:VCALENDAR 
VERSION:2.0 {...snip...}'>, 'log_logger': <Logger 
'txdav.caldav.datastore.scheduling.implicit'>, 'log_time': 
1554185763.126154, 'log_namespace': 
'txdav.caldav.datastore.scheduling.implicit'}: 'ascii' codec can't 
decode byte 0xc3 in position 1071: ordinal not in range(128)

Position 1071 is: SUMMARY:Abstimmung unserer Aktivit\xc3\xa4ten

This happens if I receive an external invitation by email to an event 
created with outlook. I use thunderbird as caldav client.

There seem to be two problems:

- Only one ORGANIZER is allowed in an iCalendar object

- ascii' codec can't decode byte 0xc3 in position 1071

How can I avoid the error?

Is this a misconfiguration? If yes - on the server or the client?

If it is a bug, should I report this as a bug against the debian package?

Kind regards

Dominik
