Block Octant-12378

429/686

𜶲 is a block mosaic that packs a squat picture into one text character. Kaypro CP/M screens used 2 4 character tiles as pixels; adjoining octants can compose a larger terminal image. Its unusual name doubles as a tiny cell map.

Text symbol

What 𜶲 means

Five of its eight cells in a 2 4 tile are filled.

An octant is a rectangle of eight solid-or-empty cells arranged in two columns and four rows; the digits 1, 2, 3, 7, and 8 mark this character's filled positions.

By 1984, Kaypro graphics on computers running CP/M used 2 4 character cells as pixels. The historical mapping pairs this pattern with Kaypro's reverse-video code B4; reverse video swaps the screen's foreground and background.

Adjacent octants can join like pixels into a larger terminal image.

Questions people ask

Why does this octant show as a box or blank?

It may be a font or terminal-support issue. As of 2026, some terminals draw octant shapes themselves, while others rely on a font that includes them; if neither supports the character, the app may show a box or blank.
