What ⒋ means
It introduces the fourth entry.
At line start, it works like “4.” before an item; alone, it can look like an unfinished outline.
Why is ⒋ one character?
It preserves a numbered bullet as one character.
Unicode describes the full-stop number forms as compatibility symbols derived from legacy East Asian character sets and intended as numbered bullets.
A Unicode working document maps ⒋ to the fourth entry in a group called “ARIB numbers period,” a set of number-and-period marks.
Don't confuse it with
24.
④Why use ⒋ instead of 4.? ⒋ is one character; 4. is two plain-text characters and easier to type. Some text systems turn it into “4.”.
Circled Digit Four
How is ⒋ different from ④? ④ is a circled numeral; it can mark the same list position through a different visual convention.
Questions people ask
1Why does ⒋ 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.
