Should not have bought from FileMaker Inc.
I assumed that FileMaker Pro from FileMaker Inc. would support Arabic (right-to-left scripting) since I've been using Bento for Mac & iOS for years, which do support Arabic and are made by FileMaker Inc.
And here's the kicker, even FileMaker Go supports Arabic!
I've wanted FileMaker for a couple years, and when 12 came out and then the current 50% off sale, I couldn't pass it up. I should have read the fine print first. I've since learned that I should have bought FileMaker from winsoft.fr, which is the company that sells FM that supports Arabic. (but they don't have the 50% sale).
