docs: Sets the character orientation mode to be used from now on.
  
  Can either be set to a concrete value (true meaning right-to-left,
  false meaning left-to-right) or to <code>null</code> which means that
  the character orientation mode should be derived from the current
  language (incl. region) setting.
  
  After changing the character orientation mode, the framework tries
  to update localization specific parts of the UI. See the documentation of
  {@link #setLanguage} for details and restrictions.
  
  <b>Note</b>: See documentation of {@link #setLanguage} for restrictions.
  
  @param {boolean|null} bRTL new character orientation mode or <code>null</code>
  @return {sap.ui.core.Configuration} <code>this</code> to allow method chaining
