iCal feed throwing syntax errors with newline character

iCal feed throwing syntax errors with newline character

Hi

I am trying to share my calender report with google calender using ical(using two fields Address and Datebooked), the Address is a multiline field, when this is added to the ical URL, google calender comes back with syntax error. I put ical URL through an online validator, and its is pointing to an error when there is an newline from my address field. When this is removed the ical feed works. 

Is it possible you can fix this by encoding the newline character so its readable in the ical format or if poss suggest an alternative way.

Thanks
