Is a way avoiding the driver crash with unicode data?

The following exception occures when the select
statement is issued through the Hibernate. The table
contains some unicode data. After I remove one entry
with the data:

擦亮眼睛
哈达
拉帮结派

No exception occurs. No error message is in the PG log
file. How can I avoid such exception happend again?

org.springframework.jdbc.UncategorizedSQLException:
(Hibernate operation): encountered SQLException [An
I/O error occured while sending to the backend.];
nested exception is org.postgresql.util.PSQLException:
An I/O error occured while sending to the backend.
org.postgresql.util.PSQLException: An I/O error
occured while sending to the backend.
