Unity Arabic Text (WIP until I have a project for it)

You can use this tool to add Arabic text support in Unity 2018. There are still some edge cases I haven't solved yet, but it works.

If this tool doesn't work for your need, use the more feature-complete Arabic Support tool in the Unity Asset Store.
