How do I work with Unicode scalars and extended grapheme clusters?

Working with Unicode Scalars and Extended Grapheme Clusters in Swift

In Swift, Unicode scalars represent a single Unicode character, while extended grapheme clusters represent what a user perceives as a single character (which could consist of multiple Unicode scalars). Understanding both is crucial for correctly handling strings, especially when dealing with complex characters.

Here’s an example of how to work with these concepts in Swift:

// Example in Swift let singleScalar: String = "\u{1F600}" // ???? let combinedGrapheme: String = "e\u{0301}" // é // Unicode Scalars for scalar in singleScalar.unicodeScalars { print(scalar) // Output: U+1F600 (grinning face) } // Extended Grapheme Clusters for character in combinedGrapheme { print(character) // Output: é }
