# titlecaseMapping

The titlecase mapping of the scalar.

## Declaration

```swift
var titlecaseMapping: String { get }
```

## Discussion

Discussion This property is a String, not a Unicode.Scalar or Character, because some mappings may transform a scalar into multiple scalars or graphemes. For example, the ligature “fi” (U+FB01 LATIN SMALL LIGATURE FI) becomes “Fi” (U+0046 LATIN CAPITAL LETTER F, U+0069 LATIN SMALL LETTER I) when converted to titlecase. This property corresponds to the “Titlecase_Mapping” property in the Unicode Standard.
