East Asian languages like Chinese and Japanese are natively and traditionally written in a vertical orientation, top to bottom and right to left. I need this. Problem is the only program that I know of supporting this is Word. I am not a Windows user.
I need a processor or editor, any sort, that supports vertical orientation. It doesn't have to be something like Pages, it could be those more like those markdown processors like Ulysses and iA Writer, or monospace coding apps like Atom for all I care. Or something like Evernote that's not exactly a pure word processor.
Preferably though, I don't want to venture into pdf. Or having to use hack-ish methods like forcing the width.
