1420243 - Some events (anniversary, death date) are not imported from a Nextcloud CalDAV server

Status: RESOLVED INCOMPLETE

(Calendar :: Provider: CalDAV, defect)

Description

[juergen.edner]

Beside a birthday and a death date an anniversary date can be defined in a Nextcloud (v12.0.3) contact record, which are all automatically be used to create calendar events in a calendar called "contact birthdays". An anniversary event record, e.g. looks like this:

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Sabre//Sabre VObject 4.1.2//EN
CALSCALE:GREGORIAN
BEGIN:VEVENT
DTSTAMP:20171031T145414Z
DTSTART;VALUE=DATE:20001120
DTEND;VALUE=DATE:20001121
UID:2e1d9687-5a7c-4982-9ad3-bc2cae595476
RRULE:FREQ=YEARLY
SUMMARY:Mr.Tom Jones (∞­2000)
TRANSP:TRANSPARENT
BEGIN:VALARM
TRIGGER;VALUE=DURATION:-PT0M
ACTION:DISPLAY
DESCRIPTION:Mr.Tom Jones (∞2000)
END:VALARM
END:VEVENT
END:VCALENDAR

If you now add this calendar to Lightning, its content, usually birthdays, are correctly displayed as e.g. "Mr.Tom Jones (*1970)", except death and anniversary records. These kind of records are not imported and displayed in the subscribed calendar. My assumption is, that the special characters which are used in the SUMMARY and DESCRIPTION fields to mark these kind of events, is causing a problem during the import.

Anniversary events are usually containing the infinity symbol (hex:e29a) in front of the year, e.g. "(∞­2000)", death dates are containing a cross symbol (hex:e280) in front of the year, e.g. "(†2010)". 

I've checked the local calendar database but the records have definitely not been imported. I've also checked the web servers log file and the error console within Thunderbird but no errors were logged during a synchronization attempt.
