There are derivatives, too, like Adrian Siekierka's funscii: <a href="https://github.com/asiekierka/funscii">https://github.com/asiekierka/funscii</a><p>Which in turn has its own (albeit not up to date) forks like <a href="https://github.com/Wuerfel21/funscii">https://github.com/Wuerfel21/funscii</a> .<p>Unscii itself has approximately 3200 glyphs of its own, some adapted or taken from various old home computing and arcade platforms. To that it supplements from FixedSys Excelsior, which itself has about 5800 glyphs (but where some overlap). There's a "full" version that then further supplements from (an old version of) GNU Unifont as well.<p>The adaptation of 8by8 characters is fairly systematic: <a href="https://github.com/jdebp/unscii/blob/2.1.1f/src/unscii.txt#L214">https://github.com/jdebp/unscii/blob/2.1.1f/src/unscii.txt#L...</a><p>Unsung items in the source include font files for the old platforms, such as the Commodore PET for example.
Amusingly, the Atari arcade font has no letter 'N': <a href="https://github.com/viznut/unscii/blob/main/src/font-arcade.txt#L124">https://github.com/viznut/unscii/blob/main/src/font-arcade.t...</a><p>(For anyone wanting to fix that: <a href="https://github.com/jdebp/unscii/commit/d9c29ca59bfda4d72446c9c754a7cbbee523e796">https://github.com/jdebp/unscii/commit/d9c29ca59bfda4d72446c...</a> )
