@NikkiSchwartzVB If you do create a .yaml file per client then consider creating a folder in Editorial called clients and the change Donald_Trump.yaml to clients/Donald_Trump.yaml in your read and write logic. This will keep your clients out of your Documents folder.
Which characters do you have trouble with? Do simple English letters work, or do they go missing too?
Also I assume you're using the "Fountain to PDF" workflow from the "Extra Workflows" section of the Editorial docs? I did some quick testing and it seems to work for me. (With some emoji I get an error from the workflow, but I didn't get any missing characters.)
I just bought editorial so that I could edit my orgmode files, I've been viewing them on the iPhone via drop box for some time. To be clear I don't expect editorial to fully implement org mode, but the ability to format it with the left swipe, as it does with md would be nice.
