> Now spark use `ObjectInspectorCopyOption.JAVA` as oi option which will convert any string to UTF-8 string. When write non UTF-8 code data, then `EFBFBD` will appear.
> We should use `ObjectInspectorCopyOption.DEFAULT` to support pass the bytes.
> Here is the way to reproduce:
> 1. make a file contains 16 radix 'AABBCC' which is not the UTF-8 code.
> 2. create table test1 (c string) location '$file_path';
> 3. select hex(c) from test1; // AABBCC
> 4. craete table test2 (c string) as select c from test1;
> 5. select hex(c) from test2; // EFBFBDEFBFBDEFBFBD
