Well then :) You might also like the report “Character Set Issues for Ada 9X”[1] from 1989, the only online source I know that goes into any sort of detail about the old ISO 10646 draft before it was essentially replaced[2,3] with Unicode. (Other references about that beast are welcome!) The only trace of it in current use looks to be the term “plane” for a naturally-aligned set of 2^16 code points, originally from a base-256 sequence of group / plane / row / cell.

  Wow, this is crazy, thank you so much for sharing! I love reading history like this! :D Every time I read about the history of character encodings I feel like I learn about a new encoding standard that attempted to standardize things. Reading about this led me to reading more about ASCII as well. I learned it was derived from the 1924 ITA2 standard which was itself derived from the "Baudot" printing telegraph encoding from 1874! It always amazes me how much history surrounds this topic! [1] Also, that DTIC site is such a treasure trove of great information! :D [1] http://www.baudot.net/docs/smith--teletype-codes.pdf http://www.baudot.net/docs/smith--teletype-codes.pdf
