What means
Use the hexadecimal reference in HTML.
An octant is an eight-part mosaic cell, arranged here as two columns and four rows. The digits in this tile’s name identify its five filled parts; neighboring cells can join into a larger pixel image.
By 1984, Kaypro II computers used 2×4 semigraphics to plot pixels on a text display. Unicode retained these legacy characters for conversion and compatibility with old computer data.

1Why does this octant show as a box?
Your font or terminal lacks a usable glyph. As of 2026, Cascadia Code and Nerd Fonts include octant characters, but the terminal also needs Unicode 16 support.
