MtScript
A multi-lingual text editor that enables using several different writing systems (Latin, Arabic, Cyrillic, Greek, Hebrew, Chinese, Japanese, and Korean) in the same document. MtScript provides typical editing functions such as insertion and deletion, even for text containing portions of writing in opposite directions. In addition, MtScript allows the user to explicitly associate portions of the text with a particular language, and to associate keyboarding rules with any language. Different types of character sets (single byte, multiple-byte) can also be handled.
