What ㌶ means
It means a hectare, a unit for measuring land. Japanese writes the word as ヘクタール; ㌶ fits those five Japanese characters into one square cell, so the square changes the layout, not the measurement.
Why is it one square cell?
It saves space in Japanese typesetting. As of 2026, Japanese typesetting references document square-unit forms in newspapers and other space-constrained print, where a compact label could fit a narrow line. The Japanese word ヘクタール comes from French hectare; a Japanese dictionary cites 1877 as an early example of the word in Japanese.
Compact Japanese unit notation, more at home in typesetting than ordinary prose.
For plain searchable text, use “ha” or ヘクタール; ㌶ can be unfamiliar outside Japanese square-cell typography.

1Why does ㌶ 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.
