How to change file encoding table in java

I have my code to check encoding table:

System.out.println("enc. table: "+System.getProperty("file.encoding") +
          "enc. table: "+new java.io.OutputStreamWriter(new java.io.ByteArrayOutputStream()).getEncoding() + 
          "enc. table:" + java.nio.charset.Charset.defaultCharset().name());

When I start my from windows I get text file with cp1250, when 开发者_如何转开发I start from my embedded system I get text file with cp852. In windows I have set code page 852. In Eclipse I have set cp852. Some solution?

You should really be specifing the required encoding on the OutputStreamWriter.

new OutputStreamWriter(outstream, "cp852");
