1. A teleprinter system for Arabic-Farsi languages comprising: means for generating a succession of 5-bit codes each representing an Arabic character of the Arabic-Farsi language or one of a plurality of standard teleprinter characters including teleprinter numerals, punctuation, and command characters, without regard to the form of the Arabic characters; means for inserting one of at least three 5-bit codes into the succession of 5-bit character codes to identify at least one subsequent character code as being in one of at least three predetermined groups of characters associated with the inserted one of the three 5-bit codes; means for receiving and storing the 5-bit code for at least two successive characters; means responsive to the stored 5-bit codes for classifying each received character as one of a plurality of predetermined character types; means for generating a second code identifying each stored 5-bit code representing an Arabic character as one of four possible Arabic character forms in response to the classified type of the character immediately preceding and immediately following the first stored of the characters; means for displaying in its proper form and position each Arabic character represented by a stored 5-bit code in response to said second code and the stored 5-bit code, including means for displaying successive characters in the same position in response to an indication from the classifying means that a character to be displayed is of a character type for which the display position is not to change.

The teleprinter system of claim 1 wherein said classifying means comprises means for specifying each received character as a character of the type that joins to the preceding or following character in a given word, a character of the type that does not join the following character in a given word but does join the preceding character, a character of the type that does not join either the preceding or following character, a character of the type that does not cause the movement of the display to another space, or a character of the type that specifies a teleprinter operation command.
