charset cp852和ISO 8859-2

Question

Is it possible that while loading characters from .dbf file with charset cp852 to

ArrayList<Map<String, Object>>();

and save that to xml file with encoding ISO 8859-2 can occur data loss?

In internet explorer and java collections all charset seems to be ok, but when I add data from xml to database I lose my letters like ą , Ą , ś , Ś

Answer 1

yes, it is pretty much possible as displayed on this code (though it will be fine if you only want to export simple letter).

public class Sample {
    public static void main(String[] args) throws Exception {
        // try to print Upper case A with ogonek
        System.out.println(new String(new byte[] {(byte) 164}, Charset.forName("IBM852"))); // <--- will print the correct character
        System.out.println(new String(new byte[] {(byte) 164}, Charset.forName("ISO-8859-2"))); // <--- will print something else
    }
}

the result in my place will look like this

Ą
