Properties.store produces question marks

Question

Hi all,
I'm using java 1.4. My code needs to write a property file, with some user input that contains international chars. The code needs to handle input in all languages, regardless of the system global locale or encoding settings.
I'm using:
props.setProperty("x", "<some international string>");
props.store(myFileStream);I expected the output to be something like:
x=\u1234\u4321...
But the output in the file is:
x=?????
On the other hand, if I manually create the prop file like so:
x=\u1234\u4321...
Then the following code works as needed:
props.load(myFileStream)
props.getProperty("x")How do I make Properties.store behave as expected?

Answer 1

I can't reproduce this here:
this SSCCE:
package snippet;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Properties;
public class SSCCE {
     public static void main(final String[] args) throws IOException {
          Properties prop = new Properties()
          prop.put("foo", "&#3585;&#3586;&#3587;");
          FileOutputStream os = new FileOutputStream("foo.properties");
          prop.store(os, "foo");
          os.close();
}Produces this output for me:
#foo

foo=\u0E01\u0E02\u0E03Where do you get your String from? Is it in the .java source file? If so, do you compile your code with the correct source encoding?
Edit: and do you use an OutputStream or a Writer? I.e. what type is myFileStream?
