# isCased

A Boolean value indicating whether the scalar is considered to be either lowercase, uppercase, or titlecase.

## Declaration

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

## Discussion

Discussion Though similar in name, this property is not equivalent to changesWhenCaseMapped. The set of scalars for which isCased is true is a superset of those for which changesWhenCaseMapped is true. For example, the Latin small capitals that are used by the International Phonetic Alphabet have a case, but do not change when they are mapped to any of the other cases. This property corresponds to the “Cased” property in the Unicode Standard.
