Unicode Scalars and Code Points

Access the underlying scalar values of text.

Unicode Scalars

A Unicode scalar is a single code point in the Unicode standard, represented by Unicode.Scalar. Characters are built from one or more scalars.

let scalar: Unicode.Scalar = "A"
print(scalar)
print(scalar.value)

Each scalar has a numeric .value: its Unicode code point as a number. The letter A is 65.

let a: Unicode.Scalar = "A"
let z: Unicode.Scalar = "Z"
print(a.value, z.value)
