Labels: pull-request-available (was: )
> Fix translate() to distinguish deletion from literal U+0000 replacement
> -----------------------------------------------------------------------
>
> Key: SPARK-57747
> URL: https://issues.apache.org/jira/browse/SPARK-57747
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.2.0
> Reporter: Spyros Pavlatos
> Priority: Major
> Labels: pull-request-available
>
> {{translate}} currently treats {{U+0000}} ({{{}\u0000{}}}, {{{}X'00'{}}}) as
> a deletion marker in its internal mapping logic. Because of this, a valid
> request to replace a character with a literal NUL is misinterpreted as
> “delete this character,” producing length 0 instead of length 1 output for
> that position.
> This ticket fixes that specific ambiguity so literal {{U+0000}} replacement
> is preserved as data, not interpreted as delete. The change should be applied
> consistently across Catalyst dictionary construction,
> {{{}UTF8String.translate{}}}, and any codegen/collation translate paths, with
> regression tests that assert {{translate(..., ..., '\u0000')}} emits a real
> NUL character.
