@chenghao-intel First of all thanks for all your comments and thoughts. I
guess the `UTF8String` is only used in SPARK SQL, isn't it? Because of that I
think the behavior should be similar to a database and not to JAVA. But I don't
know if this should be achieved by modifying the SQL layer or this type
implementation.
What do you think?
