The aixterm command supports Arabic and Hebrew, which are bidirectional languages. Bidirectional languages have the ability to be read and written in two directions, such as from left to right, and from right to left. You can work with Arabic and Hebrew applications by opening a window specifying an Arabic or Hebrew locale.
See the aixterm command in the AIX 5L Version 5.1 Commands Reference for the exact syntax.
