-----------------------------------
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()`
