What ㊋ means
Read the circled 火 as Tuesday in a Japanese weekday list. The circle makes the character a one-cell calendar label. In Japanese, 火 by itself means fire, and 火曜日 is Tuesday, literally “fire day.” Fonts can draw the circle and strokes differently without changing the reading.
The Japanese seven-day naming cycle links the Sun and Moon with the five planets visible to the naked eye; 火 corresponds to Mars. A Japanese record from 998 is the earliest cited evidence for this weekday calendar, while a later note points to an earlier 919 precursor.
Neutral shorthand for Japanese weekday tables.

1Why 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.
