What I did: Clicked on Share > Send by Email > Selected Note. I am using Outlook for Mac.
What happened: Note exports fine, but if there is an ampersand anywhere in the agenda body, the export truncates at that point.
What I expected: No truncation.
Things that might be helpful to know (Agenda version, OS and model, etc): Latest builds of Mojave, Agenda, and Outlook 2016 for Mac.
