### Describe the bug initcap was updated in this PR: https://github.com/apache/datafusion/pull/13752 `InitcapFunc` is reporting that the return type will be `Utf8` but if the argument is an `Utf8View` then the actual returned values are also `Utf8View` (as I would expect) so we have a difference between the expected and returned types. I think this is a very easy fix. On part that I could use some help with from someone more experienced with the Utf8View is this: in `get_optimal_return_type` macro we state that `DataType::Utf8View` has an optimal return type of of `Utf8` during the macro invocation. Is this the best type? Why would we not want to return a Utf8View? ### To Reproduce Call `initcap` with a Utf8View argument. ### Expected behavior No error. Currently I get this error: Exception: Arrow error: Invalid argument error: column types must match schema types, expected Utf8 but found Utf8View at column index 0 ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
