             Summary: Make ErrorUtils string size checks byte-aware
                 Key: SPARK-55930
                 URL: https://issues.apache.org/jira/browse/SPARK-55930
             Project: Spark
          Issue Type: Bug
          Components: Connect
    Affects Versions: 4.1.1
            Reporter: Xi Lyu


We should replace character-length checks with UTF-8 byte size checks when 
enforcing
the gRPC metadata size limit. Multi-byte characters (e.g. CJK) can cause
length-based checks to undercount the actual byte size sent on the wire.
