This character is a Decimal Number and is commonly used, that is, in no specific script. The codepoint has the decimal value 1.
The glyph is not a composition. Its East Asian Width is narrow. In bidirectional text it is written as European number from left to right. When changing direction it is not mirrored. This number joins with other adjacent letters and numbers to form a word. U+0031 forms a number with similar characters, which prevents a line break inside it. The glyph can be confused with one other glyph.
This character is designated as an emoji. It will be rendered as monochrome character on conforming platforms. To enable colorful emoji display, you can combine it with Variation Selector-16: 1️ See the Emojipedia for more details on this character’s emoji properties.
El Wikipedia tiene la siguiente información acerca de este punto de código:
El uno (1) o su apócope un son el primer o segundo —tema en discusión— número natural y es el número entero que sigue al cero (0) y precede al dos (2). El uno (1) no es número primo ni número compuesto.
1 (uno, unidad) es un número que representa una única entidad. 1 es también un dígito numérico y representa una única unidad de conteo o medida. Por ejemplo, un segmento de línea de longitud unitaria es un segmento de línea de longitud 1. En convenciones de signo donde el cero no se considera ni positivo ni negativo, el 1 es el primer y más pequeño número entero positivo.[2] A veces también se considera el primero de la secuencia (matemática)|secuencia infinita de números naturales, seguido del 2, aunque según otras definiciones 1 es el segundo número natural, después de 0.
La propiedad matemática fundamental del 1 es ser una identidad multiplicativa, lo que significa que cualquier número multiplicado por 1 es igual al mismo número. La mayoría de las propiedades del 1, si no todas, pueden deducirse a partir de ésta. En matemática avanzada, una identidad multiplicativa a menudo se denota 1, incluso si no es un número. Por convención, el 1 no se considera un número primo; esto no se aceptó universalmente hasta mediados del siglo XX. Además, 1 es la menor diferencia posible entre dos números naturales distintos.
Las propiedades matemáticas únicas de este número han llevado a su uso único en otros campos, que van desde la ciencia a los deportes. Suele designar lo primero, principal o superior de un grupo.
