Dieses Zeichen ist ein Other Number und wird allgemein verwendet, das heißt, in keiner speziellen Schrift. Der Codepunkt repräsentiert die Ziffer 1.

Das Zeichen ist keine Zusammensetzung. Es hat keine zugewiesene Weite in ostasiatischen Texten. In bidirektionalem Text handelt es als Other Neutral. Bei einem Richtungswechsel wird es nicht gespiegelt. Wenn seine ostasiatische Weite „schmal“ ist, bildet U+278A mit ähnlichen Zeichen ein Wort, das in sich Zeilenumbrüche verbietet. Andernfalls erlaubt es Zeilenumbrüche um sich herum, außer in einigen numerischen Kontexten.

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of unit length is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0.

The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the smallest possible difference between two distinct natural numbers.

The unique mathematical properties of the number have led to its unique uses in other fields, ranging from science to sports. It commonly denotes the first, leading, or top thing in a group.
