Abstract: A computer system which creates many styles of character sets whose characters represent either a group of five-bit or a group of eight-bit binary-coded decimal numbers. The character sets are used for common communication, other than handwriting, by people or machines, in any sensible medium. Having interchangeable eight-bit and five-bit character sets provides transparent interface between communication for people, and communication for technical and machine purposes. The purpose of this system is to create a single character set which will express all of the languages of the world. The system is comprised of three primary processes: designing, coding, and formatting the binary-coded decimal characters. When supplied with cleartext information, the system converts the information and expresses it with the created character set, in any sensible medium. It converts each character of the cleartext information to the corresponding character of the created character set.
