After creating an event with dot (.), slash (\), colon(:) in the name all events disappear from the Calendar view

Steps to reproduce:

1. Have an application that uses fullcalendar macro
2. Add multiple events and observe them in the calendar
3. Add an event that has in name dot or slash or colon ( ex. New.Event )
4. Observe the calendar

Expected result: all the events are displayed.

Actual result: none of the events are displayed, not even the ones that could be seen before.
