Everything old is new again. This reminds me of ZSCII, which was how Infocom games encoded string data to fit ~100kb of text data into a Commodore 64, packing 3 characters into every 2 bytes. --first byte------- --second byte--- 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 bit --first-- --second--- --third-- The 5-bit character encoding was one of three character sets: Z-char 6789abcdef0123456789abcdef current -------------------------- A0 abcdefghijklmnopqrstuvwxyz A1 ABCDEFGHIJKLMNOPQRSTUVWXYZ A2 ^0123456789.,!?_#'"/\-:() -------------------------- Z-char 0 was space in all character sets, z-char 1 was newline, z-chars 2 and 3 switched to one of the other character sets depending on which one you were already in for the next character only, and z-chars 4 and 5 switched permanently, the "shift-lock". https://inform-fiction.org/zmachine/standards/z1point0/sect03.html https://inform-fiction.org/zmachine/standards/z1point0/sect0...
