### Current behavior Python tuple hashing iterates Unicode code points, while Java String hashing iterates UTF-16 code units. Characters outside the basic multilingual plane therefore produce different tuple hashes in the Python and JVM engines, which can route the same hash-shuffle key to different workers. Before: the emoji key hashes to 128543 in Python and 1772930 with Java semantics After: both engines hash the key to 1772930 ### Steps to reproduce On `50321e403c82df299a13deb50a7f9849dd93bdba`, hash a tuple with one string field containing `😀`. Observed values: ```text python_tuple_hash=128543 java_compatible_tuple_hash=1772930 ``` ### Expected behavior Python string tuple hashing should iterate UTF-16 code units so hash shuffle routing matches the JVM for every valid Unicode string. -- This is an automated message from the Apache Git Service.
