Answering the checklist above: 1. **Problem / what this adds**: three new fuzzy string-matching scalar functions — `jaro`, `jaro_winkler`, `jaccard_similarity`. This continues #60799, whose `levenshtein`/`damerau_levenshtein` have since landed separately via #60412 and #65278, so those two are dropped here to avoid duplicating them. 2. **Behavior changed**: none — purely additive, no existing function or code path is touched. 3. **Features added**: see (1). `jaro_winkler` reuses the `jaro` implementation rather than duplicating it, and `jaccard_similarity` is a character-set Jaccard index (ASCII bitset / UTF-8 hash set) matching ClickHouse's `stringJaccardIndex`. All three have UTF-8 support, FE constant folding, and an input-length guard. 4/5. **Refactor / optimization**: not applicable, no existing code was refactored. -- This is an automated message from the Apache Git Service.
