Missing text in personal events
Whenver I try to put the following characters in a personal event, they do no appear in the calendar.
In fact, any time the "less than" symbol is entered in the text, it and any other characters adjacent to it do not appear in the text.
My guess is that these are stripped since they could be interpreted as part of HTML or XML. However, I can't find any documentation to help me know the correct syntax to use (an escape code of some sort) to allow these characters to display.
Any help or suggestions greatly appreciated.
