Support creating and displaying multi-lingual events
RFC 5545 supports having several SUMMARYs and DESCRIPTIONs for a VEVENT, that represent different LANGUAGE parameters. The multi-lingual iCalendar objects are useful for public calendars, where the event publisher wants to anticipate multi-lingual audience for some of the published events.
• Extend the component editor to create multi-lingual events
• Teach Evolution to honour the language preference of the user, when rendering iCalendar objects, if not done yet.
