Limitations
ArbortextEditor's document directionality support has the following limitations:
The ArbortextEditor user interface (menus, dialog boxes, and so forth) does not have a RTL layout in the Arabic and Hebrew locales.
Generated text in areas like lists might not display as desired in a RTL document. For example, if the generated text for a numbered list is 1. in a LTR document, it would display as .1 in a RTL document.
If any sort of markup is applied to the first part of embedded reversed text, that text is not displayed in the correct order.
Spaces are not shown in embedded reversed text, regardless of the setting of the set showspaces command.
