My simple test input of
[{"field1": 10, "field2": "hello"},{"field1": 12, "field2": "byte"}]
is encoded like this (according to emacs hexl-mode):

I just used iconv to convert the file from utf-8 to utf-16.
> Unable to read jsons in charset different from UTF-8

> Key: SPARK-23410
> URL: https://issues.apache.org/jira/browse/SPARK-23410
> Project: Spark
> Issue Type: Bug
> Components: Input/Output
> Affects Versions: 2.3.0
> Reporter: Maxim Gekk
> Priority: Major
>
> Currently the Json Parser is forced to read json files in UTF-8. Such
> behavior breaks backward compatibility with Spark 2.2.1 and previous versions
> that can read json files in UTF-16, UTF-32 and other encodings due to using
> of the auto detection mechanism of the jackson library. Need to give back to
> users possibility to read json files in specified charset and/or detect
> charset automatically as it was before.
