Block Octant-15678

470/686

𜷛 fills five of eight spots in an octant tile used for text-grid pictures. Kaypro graphics used the 2-by-4 mosaic for pixels; it can also build terminal art and compact charts. Cascadia Code added all octants in April 2024; as of 2026, support varies by font and terminal, so 𜷛 may show as a box or blank.

Text symbol

What 𜷛 means

One text cell acts as a tiny pixel canvas.

Its 2-by-4 grid has eight spots; “15678” names the five filled. Lined up with other octants, it forms larger images.

Semigraphic blocks let home computers imitate pixels in the 1970s and 1980s. In January 1984, a Kaypro 10 manual describes plotting in 2-by-4 text cells and reversing light and dark to reach every pattern; this tile belongs to its reverse graphics set.

Why does 𜷛 show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
