# init(string:encodingInvalidCharacters:)

Creates a URL instance from the provided string, optionally IDNA- and percent-encoding any invalid characters.

## Declaration

```swift
init?(string: String, encodingInvalidCharacters: Bool)
```

## Parameters

- `string`: A URL location.
- `encodingInvalidCharacters`: A Boolean value that indicates whether the initializer attempts to encode any invalid characters in string.

## Discussion

Discussion If encodingInvalidCharacters is true, this initializer tries to encode the string to create a valid URL. If the URL string is still invalid after encoding, the initializer returns nil.
