From NJStar Software:
NJStar Communicator is Chinese, Japanese, and Korean (CJK) communication software, as NJStar Communicator gives you both easy viewing capabilities and allows for CJK character input in normal Windows applications. It also comes with a universal code converter, which converts between all CJK language codes (including the new Unicode) as well as the GIF picture format. (It can automatically detect CJK code and convert a whole Chinese, Japanese, or Korean book into GIF picture files.) NJStar Express Mail, which is bundled with the software, allows users to send Chinese (both simplified and traditional), Japanese, and Korean email messages with no corruption by using automatic text encoding. You can even attach CJK message in GIF picture format so that the receiver can read the message instantly without the need for a multilingual support program.
Version 2.5 includes added Cantonese support, new command line options, enhanced mail features, improved UTF8 detection, and extended Korean support.
