How can we access or set the Indic options in Illustrator CC by script? (Middle East Character Formats, Language= Arabic etc.)

  In Illustrator CC you can set the Show Indic options by the User interface.

When accessing the document by scripting (or wants to create new Characterstyles or Paragraphstyles supporting the Middle Eat Character formats) these options are not there?

How van we select these options or how can we set the Indic Options by scripting?
