Abstract
Computer applications with a need for Farsi Language information processing suffer from the lack of several fundamental standards, of which the most pressing and far-reaching ones relate to an information representation and interchange code and a computer keyboard layout. In this paper, systematic extensions of the ISO (International) Standards Organization) 7-bit and 8-bit standard codes are proposed in connection with the Farsi language. The proposed standard codes possess a number of desirable properties which systematize and simplify the processing of Farsi and mixed (Farsi/Latin) information. Design considerations and technical justifications for the codeword selection problem are presented. A standard bilingual keyboard layout, which maintains the conventional typewriter format, to the extent possible, while eliminating its short-comings and inconsistencies, is proposed. Justifications for the various design decisions in arriving at the proposed layout are also given.
