If you want to add "RTL" text as "auto" (text direction is based on text characters used):

File: WikiEditor/modules/jquery.wikiEditor.js

line: 458

Add: .attr( 'dir', "auto" )

This will only fix it for adding the text. You will still need to use a "div" in order to actually display the text as RTL.

The text direction of the editor is based on the primary content language, not on the characters used. It should not be automatic.
