# init(bytes:encoding:)

Creates a new string equivalent to the given bytes interpreted in the specified encoding. Note: This API does not interpret embedded nulls as termination of the string. Use String?(validatingCString:) instead for null-terminated C strings.

## Declaration

```swift
init?<S>(bytes: S, encoding: String.Encoding) where S : Sequence, S.Element == UInt8
```

## Parameters

- `bytes`: A sequence of bytes to interpret using encoding.
- `encoding`: The encoding to use to interpret bytes.
