Why does Swift's Character type support extended grapheme clusters instead of just Unicode scalars?

ABecause <code>Character</code> only supports ASCII characters

BBecause Unicode scalars are deprecated in Swift

CTo improve performance by storing fewer bytes

DTo correctly represent human-readable characters that may combine multiple Unicode scalars

Step-by-Step Solution

Solution:

Step 1: Understand extended grapheme clusters
Extended grapheme clusters allow multiple Unicode scalars to combine into a single visible character, like accented letters or emoji sequences.
Step 2: Reason why Swift uses this for Character
Swift's Character type models what users perceive as a single character, which may be multiple Unicode scalars combined.
Final Answer:
To correctly represent human-readable characters that may combine multiple Unicode scalars -> Option D
Quick Check:
Character models user-visible characters, not just scalars [OK]

Quick Trick: Character represents visible characters, not raw Unicode scalars [OK]
