我为法语口音字符配置了DB2数据库，并且通过DB2命令行工具，以下两个SQL语句都成功返回包含法语重音字符的结果。
select * from ca_cpo_inventory where dealer_id = 46170 and locale = 'fr'
和
select * from ca_cpo_inventory where dealer_id = 46170 and locale = 'en'
但是在JEE代码中，locale ='fr'SQL通过Hibernate和PreparedStatement正常工作，但locale ='en'导致以下异常。 （注意：只有在英文行中有法语字符时才会出现异常。如果结果集中没有法语字符，则SQL工作正常）。
相同的代码用于运行两个SQL，所有不同的是语言环境。

通过PreparedStatement调用时： com.ibm.db2.jcc.c.SqlException
有谁知道有任何想法？由于SQL语句在DB2控制台中工作，我假设没有数据损坏。
