XSU Problem:Error-- Cannot map Unicode to Oracle character

Question

Hi, I am using XSU to get the resultset from database(oracle 9.2.0.6.0) as XML.When I query data from some columns and get the XMLString, they give me error -"Cannot map Unicode to Oracle character". The database charset is "US7ASCII" .
One column is storing Chinese with ''US7ASCII".When xmlString Result contianer
the column,there is "oracle.xml.sql.OracleXMLSQLException: Cannot map Unicode to Oracle character".But If xmlString Result don't container that column,it run very good.
The program container these libs: ojdbc14.jar,xmlparserv2.jar,xdb.jar,nls_charset12.jar,xsu12.jar.
The program code:
public class OracleXmlParse {
public static void main(String[] args) {
try{
DriverManagerDataSource dataSource = new DriverManagerDataSource("oracle.jdbc.driver.OracleDriver",
                    "jdbc:oracle:thin:@168.1.1.136:1521:imis","ims","ims");
String selectSQL = "select AREA_CODE,AREA_NAME,REGION_CODE,AREA_NAME_CN from CDM_AREA";
OracleXMLQuery query = new OracleXMLQuery(conn,selectSQL);
query.setEncoding("UTF-8");
String str = query.getXMLString();
System.out.println(str);
conn.close();
}catch(SQLException e){
               e.printStackTrace();
Exception:
Exception in thread "main" oracle.xml.sql.OracleXMLSQLException: Cannot map Unicode to Oracle character.
     at oracle.xml.sql.core.OracleXMLConvert.getXML(OracleXMLConvert.java:1015)
     at oracle.xml.sql.query.OracleXMLQuery.getXMLString(OracleXMLQuery.java:267)
     at oracle.xml.sql.query.OracleXMLQuery.getXMLString(OracleXMLQuery.java:221)
     at oracle.xml.sql.query.OracleXMLQuery.getXMLString(OracleXMLQuery.java:198)
     at procedure.OracleXmlParse.main(OracleXmlParse.java:34)
The column that store chinese is AREA_NAME_CN .When "selectSQL " is equal to "select AREA_CODE,AREA_NAME,REGION_CODE from CDM_AREA",the program is ok.
Please help.

Answer 1

So, What is the solution ? Is there something I can do in my code ? My program gives the exception and stops. I am not even interested to fetch the data, which are giving this error.
