**Describe the bug**
<!--
A clear and concise description of what the bug is.
-->
I have a tool that reads CSV files using DataFusion. I have a file with an
invalid UTF-8 character, apparently.
With DataFusion 16.1.0, I get this error:
```
Arrow error: Parser error: Error parsing line 27: Error(Utf8 { pos:
Some(Position { byte: 3458, line: 28, record: 27 }), err: Utf8Error { field:
14, valid_up_to: 1 } })"))
```
With DataFusion 17.0.0, I get this error:
```
ArrowError("underlying Arrow error: Csv error: Encountered invalid UTF-8
data: invalid utf-8 sequence of 1 bytes from index 2911"))
```
The first error is much more helpful because it gives me the line and field
numbers. I was quickly able to locate the bad character.
