answers 402
Normalize Japanese (JP) text to a canonical form: fullwidth↔halfwidth conversion, halfwidth-katakana folding, invisible-character removal, and whitespace cleanup — each transformation toggleable. Returns a per-change log. Use to deduplicate or match text where '東京' and 'ﾄｳｷｮｳ' must compare equal.
