A remake of a font created for the game Rex on the ZX Spectrum game from 1989

ZX82 ABCDEFG: a bicolor drolatique font generator
[dpla's ZX Spectrum edition – version 1.0 or ROIAOAIO]

294 visible text characters, in 'Extended ASCII' (U0020-FF) and a few beyond.
7 code pages (CP) to switch from, and 48 cells left unassigned (in CP 4 to 6).
Feel free to add your private glyphs, provided you retain the original mapping;
you may replace them with invisible formatting controls (e.g. for animations).
The CP switches are 7 visible control characters, applied once or indefinitely,
that is: K/B/R/M/G/C/Y → temporary; KY/BY/RY/MY/GY/CY/YY → permanent.
Please, bear in mind that my main mapping (CP 0) is based on our 6 vowels,
contrary to A-Z substitutions (like David B. Kelley's "6-Color Binary Alphabet").
This implementation uses 7 colors in ascending RGB on a white background
(hence my title: a 8-bit allusion to the ZX Spectrum Ink and Paper on screen).
Example: "Hello·world!" = "BY K RM RK MM MM GK •CR GK GM MM BM KK"
where the letters = their abbreviated color (0-6), and 'Space' / "•" = White (7).
Typically on a display, you can resort to a pair of characters (any block / bar)
but you can use the material of your choice (e.g. balloons, the air being "W"),
even derivate in color (symbols), size (micro), view (vector, 3D), language…

Recreation of the pixel font from Codemasters' "Dizzy III - Fantasy World Dizzy" (1989) on the ZX Spectrum. Note the egg character, mapped to "black circle" (U+25CF). Only the characters present in the game's tile map have been included.

Recreation of the pixel font used in the Sinclair ZX Spectrum (1982). Note the block element characters, set to their equivalent unicode points (U+2596 through to U+259F). Only the characters present in the computer's character set have been included. 

Recreation of the pixel font from Codemasters' "Rockstar Ate My Hamster" (1988). Slightly expanded with a few additional custom characters not present in the original game.

Edited (11/2016) to fix some of the characters, based on a more accurate source (C64 emulation of the game) and to include the "BLACK LARGE SQUARE" (U+2B1B) unicode character.
