Read Unicode string entry out of MS-Access though Java

Question

I'm making a small Finnish Dictionary programme use Java,so i first need to test if I can display those Unicoded Finnish words from Access to Java.
Those words reads well from my FFF.mdb by Java,but when print out on the screen,some Unicode character display in question mark-??????,by the way,I can retrieve and display my query pretty well in Ms-Access,but now problems comes to Java.
Before I print them on screen,do I need to add some filter on those unicoded finnish words after they be retrived form database,so that they can be displayed properly? thanX!
=========
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn2=DriverManager.getConnection("jdbc:odbc:FFF");
Statement stmt2=conn2.createStatement();
ResultSet rs=stmt2.executeQuery("Select * from fin_dictionary");
while (rs.next()){
//here,java can not display the finnish letters properly:
System.out.println(rs.getString("words")+",");
stmt2.close();
conn2.close();
}catch(Exception e){
System.out.println("\n SQL Exception:"+ e.getMessage()+"\n");
===end===

Answer 1

but also when I use Java's sql to instert unicode character in to the database,the character be inserted displayed in kind of "???" too. so I think there should be some method to make java handle those unicode properly.
