Abstract: A character generator for a keyboard where the keyboard has keys for entry of characters. Each key is assigned a character and each of at least some of the keys are multiple-character keys assigned multiple characters. The character generator includes a generator for generating one of the characters assigned to each of a sequence of character keys that are entered on the keyboard, there being an ambiguity as to the correct character to be generated when any multiple-character key is entered in the sequence of keys. An ambiguity resolver operates in response to the sequence of character keys that have been entered for resolving the correct character for any of the multiple-character keys in the sequence of keys that are entered.
