Set the JVM file encoding to UTF-8.

[dlvenable]

Description

Sets the JVM default encoding to UTF-8 by including -Dfile.encoding=UTF-8 in the JVM arguments. With this, we use UTF-8 by default. I found that this fixes writing to S3 with Unicode data.

Some data I got out of S3 with this fix.

{"test":"😀!!ああ😀!!ああ","id":"abc11"}
{"test":"😀!!ああ😀!!ああ😀!!ああ","id":"😀3"}
