I'm not sure if the Google calendar interprets newlines, but it looks like 121 lines per line.
So, say you want to put “Address:” / n in the details of the Google calendar.
Take 121, subtract the number of characters "Address:" and add 113 spaces to "Address:"
The following text should be on a new line.
Even easier, if the text of your submission is a PHP variable, enter a new line in php.
$description = 'Description:'.'\n';
Then the Google calendar will consider it a new line.
