i know this is almost a year old
you can use u+2800 to u+28ff to do that
every character is 2x4 pixels
add the following amount for each pixel
1 8
2 16
4 32
64 128
some example code:
local unicode = require("unicode")
local PIXEL_AMOUNTS = {
{0x01, 0x08},
{0x02, 0x10},
{0x04, 0x20},
{0x40, 0x80},
}
local function draw(pixels)
if #pixels % 4 ~= 0 then
error("image height must be a multiple of 4")
end
if #pixels[1] % 2 ~= 0 then
error("image width mode be a multiple of 2")
end
for cy = 1, #pixels, 4 do
for cx = 1, #pixels[1], 2 do
local char_co
