NisusWriter by Nisus Software, Inc. and WorldWrite by WorldSoft Corporation support World Script I, allowing them to work with Hebrew, Arabic and other languages which are entered from right to left. ClarisWorks Hebrew and ClarisWorks Arabic are not available in the United States. The U.S. version of ClarisWorks supports only WorldScript II, which allows it to work with Japanese, Chinese (both simplified and traditional) and Cyrillic. The U.S. version does not support WorldScript I, therefore it cannot work with right-to-left languages such as Hebrew or Arabic.
