I've created a module that imports calendar data exported in ical format into Zimbra calendars.
I'm using "curl" as suggested here: using curl to post ical calendars to perform the actual upload and import of the ical format file.
This works fine.
However, the description field exported has html characters in it like this:
DESCRIPTION:<p>Let'\;s have a great time - don'\;t be late</p>
And, this is displayed as if it were plain text in the Zimbra calendar. Any suggestions? Is there some way to handle this formatting issue in Zimbra?
