Description

In types.py: define CharType as SQL CHAR, but SQL CHAR is a Java String instead of Java Character.

In type_utils.py, 

org.apache.flink.api.common.typeinfo.Types.CHAR map to DataTypes.CHAR, it is wrong. Types.CHAR is Java Character.

I suggest that consider removing Char's support first.
