AutoConvert is an intelligent Chinese Encoding converter. It uses built-in functions to judge the type of the input file's Chinese Encoding (such as GB/Big5/HZ), then converts the input file to any type of Chinese Encoding you want. You can use autoconvert to automatically convert incoming e-mail messages. It can also optionally handle the UNI/UTF7/UTF8 encoding.
