[jira] [Created] (SPARK-40213) Incorrect ASCII value for Latin-1 Supplement characters

Linhong Liu created SPARK-40213:
-----------------------------------

             Summary: Incorrect ASCII value for Latin-1 Supplement characters
                 Key: SPARK-40213
                 URL: https://issues.apache.org/jira/browse/SPARK-40213
             Project: Spark
          Issue Type: Task
          Components: SQL
    Affects Versions: 3.2.2
            Reporter: Linhong Liu


the `ascii()` built-in function in spark doesn't support Latin-1 Supplement characters which value between [128, 256). Instead, it produces a wrong value, -62 or -61 for all the chars. But the `chr()` built-in function supports value in [0, 256) and normally `ascii` should be the inverse of `chr()`
