# init(_:)

Creates a Unicode scalar with the specified numeric value.

## Declaration

```swift
init?(_ v: Int)
```

## Parameters

- `v`: The Unicode code point to use for the scalar. v must be a valid Unicode scalar value, in the ranges 0...0xD7FF or 0xE000...0x10FFFF. In case of an invalid unicode scalar value, nil is returned.

## Discussion

Discussion For example, the following code sample creates a Unicode.Scalar instance with a value of an emoji character: let codepoint = 127881 let emoji = Unicode.Scalar(codepoint)! print(emoji) // Prints "🎉" In case of an invalid input value, nil is returned. let codepoint: UInt32 = extValue // This might be an invalid value. if let emoji = Unicode.Scalar(codepoint) {   print(emoji) } else {   // Do something else }
