How can I restore the original Arabic text?

[msoutopico]

It seems the "Bidirectional text" option replaces all (or most) Arabic characters with the expected Arabic presentation form (some character in range [\x{FB50}-\x{FDFF}]). However, while that can make the text readable in Sublime Text editor, it actual makes the files unusable in other tools. The plugin should provide an easy way to revert this change.

How can it be reverted? How can I restore the original text?

If that's not possible, could you provide some mapping information about what Arabic presentation forms must be replaced with each standard character?
