# isDiacritic

A Boolean value indicating whether the scalar is a diacritic.

## Declaration

```swift
var isDiacritic: Bool { get }
```

## Discussion

Discussion Diacritics are scalars that linguistically modify the meaning of another scalar to which they apply. Scalars for which this property is true are frequently, but not always, combining marks or modifiers. This property corresponds to the “Diacritic” property in the Unicode Standard.
