我有一个为法语重音字符配置的 DB2 数据库，并且通过 DB2 命令行工具，以下两个 SQL 语句都成功返回了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 可以正常工作，但 locale = 'en' 会导致以下异常。（注意：仅当英语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这两个 SQL，不同之处在于语言环境。

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