Defines a set of 153 graphic characters identified as Latin/Hebrew Alphabet, and specifies the coded representation of each of these characters by means of a single 8-bit byte. None of these characters are "non-spacing". Also prohibits the use of control functions, such as BACKSPACE or CARRIAGE RETURN for the coded representation of composite characters.
