Problem:
Since I have an RTL language, is it possible to change the WordPress Post Editor to RTL when translating posts from English to an RTL language?

Solution:
You can use the same direction of the administration language when using the WP post editor by enabling the "Set admin language as editing language" option in your profile page.
