# init(_:)

Creates a Unicode scalar with the specified numeric value.

## Declaration

```swift
init?(_ v: UInt32)
```

## Parameters

- `v`: The Unicode code point to use for the scalar. The initializer succeeds if v is a valid Unicode scalar value—that is, if v is in the range 0...0xD7FF or 0xE000...0x10FFFF. If v is an invalid Unicode scalar value, the result is nil.

## Discussion

Discussion For example, the following code sample creates a Unicode.Scalar instance with a value of an emoji character: let codepoint: UInt32 = 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 }
