It was XCCS (Xerox Character Code Standard) which is really the predecessor to Unicode. Both initially were 16 but character code spaces (Unicode was later extended) and Unicode developed by many of the same folks in Unison with Apple. I was at one time on the XCCS committee and involved with Unicode development before it was called Unicode when I was at Both Xerox and Apple. A lot of the Japanese feathers were developed with Fuji Xerox, namely vertical text support but the typing method virtually keyboard support was done by the international team headed by Joe Becker who was the Architect of all the multilingual stuff. Albert in his comment preceded my involvement some trust what he says about earlier development over what I remember.
