## Which issue does this PR close? - Closes #26125. ## Rationale for this change `SELECT char(NULL::INT)` fails with `Execution error: The argument must be an Int64 array or scalar.` where Spark returns NULL. NULL rows of an array argument already return NULL, only a NULL scalar argument reaches the error. ## What changes are included in this PR? `spark_chr` returns a NULL `Utf8` scalar for a NULL `Int64` scalar. ## What is the testing strategy for this PR? A `char(NULL::INT)` case in `spark/string/char.slt`, which fails on main with the error above. ## Are there any user-facing changes? `char` of a NULL scalar returns NULL instead of an error. -- This is an automated message from the Apache Git Service.
