----------------------------------

             Summary: `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
            Reporter: Kshiteej K


`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`.
{code:java}
>>> pc.binary_replace_slice(["hé"], 1, 2, "x")
<pyarrow.lib.StringArray object at 0x7fdbc09937c0>
[
  "hx�"
]
>>> pc.binary_replace_slice(["hé"], 1, 2, "x").validate(full=True)
Traceback (most recent call last):
  ...
ArrowInvalid: Invalid UTF8 sequence at string index 0 {code}
