Abstract
In a word processor where a text stream is input by way of a keyboard for storage and is displayed to an operator and wherein different keyboard character sets are available, means are provided for signalling the location at which an insert of one or more characters is to be added to the text stream. Means are provided for comparing the active keyboard character set in the text stream immediately preceding the location to the keyboard character set of the insert to produce a first output when the keyboard character sets compare and a second output when the keyboard character sets do not compare. The insert is entered into the text stream at the location upon generation of the first output. Upon generation of the second output a character set change code is added immediately upstream of said location to indicate the keyboard character set for the insert. Immediately following the insert a character set change code is added to indicate the keyboard character set for the text shown immediately following the insert.
