  "why": "Solution B extracts the accent stripping and length truncation logic into well-named helper functions, making the main function much easier to read. Solution A's inline length calculation uses a slightly awkward array join to determine the separator length, whereas B's string concatenation approach is more natural and readable.",
  "a_strength": "Thorough test coverage and correctly implements all requirements, including a clever (if unusual) way to handle potential non-string separator lengths.",
  "b_strength": "Excellent code organization with modular helper functions, clear error messages, and well-structured documentation updates.",
