Technical Breakdown

Case transforms are pure string operations. Identifier styles split on non-alphanumeric boundaries before rejoining. Sentence case capitalizes after terminal punctuation; Title Case capitalizes whitespace-separated words.

Unicode letters are handled via JavaScript casing where the engine supports it. Locale-specific title rules may still need human review for publishing.
