[GitHub] [arrow-rs] andygrove opened a new issue, #3656: Regression in CSV reader error handling

andygrove opened a new issue, #3656:
URL: https://github.com/apache/arrow-rs/issues/3656

   **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.
   
   
   **To Reproduce**
   <!--
   Steps to reproduce the behavior:
   -->
   
   Try reading a CSV file with invalid UTF-8 characters (perhaps try reading some random binary file).
