> `binary_replace_slice` should not work with `string` types
> ----------------------------------------------------------

> Key: ARROW-18319
> URL: https://issues.apache.org/jira/browse/ARROW-18319
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Reporter: Kshiteej K
> Priority: Major
>
> `binary_replace_slice` can give in invalid output when used with string
> types. Given that there is `utf8_replace_slice`, I think
> `binary_replace_slice` should not support string types.
> If a user actually wants to play with bytes for string type, they should
> explicitly cast to binary type and use `binary_replace_slice`.
