Retrieve the unicode from a chinese character stored in MS Access database

Question

Hi,
I have a table in MS Access database with chinese character. When I read it from my sql queries I get the "?" instead of the chinese character. When I calculate the unicode I get the 003F which is the unicode for the questionmark. How do I get the correct unicode of the chinese character?
Connection conn = DriverManager.getConnection("jdbc:odbc:myDB"); Statement stmt = conn.createStatement(); String sqlString = "SELECT Char FROM MyTable WHERE id=2"; ResultSet rs = stmt.executeQuery(sqlString); String s1 = rs.getString("Char");    // the s1 is the ? instead of the chinese character. byte[] b = s1.getBytes(Charset.forName("UTF-16")); int firstByte = 0; short anUnsignedByte = 0; String unicode = ""; for(int  n = 0; n < b.length; n++){     String temp = "";     firstByte = (0x000000FF & ((int)b[n]));     anUnsignedByte = (short)firstByte;     temp = Integer.toHexString(anUnsignedByte);     if(temp.length() == 1){ temp = "0" + temp;     }     unicode = unicode + temp; } unicode = unicode.substring(4); System.out.println("unicode: " + unicode);  //Here I get the unicode, 003f, for the question mark.

Apparently getString() is already applying the wrong encoding to the bytes which are in the data, so you can't do anything with what it returns. (This isn't surprising since it's Access you are asking about.) I suggest using the getObject() method and see what it returns. If it returns the same string then you are out of luck. But maybe you'll get lucky and it will return an array of bytes containing the correct data. Don't get too hopeful though.
