[eclipselink-users] Microsoft Access Encoding

Hello!

I try to load data from a Microsoft Access Database in Windows 7.
I use EclipseLink JPA 2.4.1.

Map<String, String> props = new HashMap<String, String>();
props.put(PersistenceUnitProperties.JDBC_DRIVER, "sun.jdbc.odbc.JdbcOdbcDriver");
props.put(PersistenceUnitProperties.JDBC_URL, "jdbc:odbc:mydb");
props.put(PersistenceUnitProperties.TARGET_DATABASE, "org.eclipse.persistence.platform.database.AccessPlatform");
// is this parameter for JDBC-ODBC bridge used???
props.put("charSet", "iso-8859-1"); 

EntityManagerFactory emf = Persistence.createEntityManagerFactory("foo", props);
em = emf.createEntityManager();

If I query my database (e.g. em.find(StringTable.class, 7)) my text encoding is destroyed in string properties in the entity. Strings like "Müller" result in in Java string like "M?ller",

It is for sure an encoding issue. But at which point or using which property do I set the correct encoding for the Access Database?
