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?

It is recent: Unicode added it in version 16.0 (2024), and phones and computers whose fonts are older than that have nothing to draw it with. The character itself is still correct and copies correctly.
