Can't this be achieved without any arrow change by using `encoding_rs_rw`
streaming adapters? e.g.
```
// Basic
fn read_utf8(filename: &str, schema: SchemaRef) -> RecordBatch {
let file = File::open(filename).unwrap();
let mut csv = ReaderBuilder::new(Arc::new(schema)).build(file).unwrap();
let batch = csv.next().unwrap().unwrap();
batch
}
// With a different encoding
fn read_other_encoding(filename: &str, schema: SchemaRef, encoding:
&encoding_rs::Encoding) -> RecordBatch {
let file = File::open(filename).unwrap();
let mut decoded = encoding_rs_rw::DecodingReader(file,
encoding.new_decoder());
let mut csv =
ReaderBuilder::new(Arc::new(schema)).build(decoded).unwrap();
let batch = csv.next().unwrap().unwrap();
batch
}
```
