JSON UTF-8 encoding errors

Question

I have some UTF8 encoding errors using JSON in JAVA:

JSONObject json = new JSONObject();
json.put("Name", "Müller");
System.out.println(json.toString());

Output:

{"Name":"M\u00fcller"}

But I would like the following:

{"Name":"Müller"}

Any suggestions? Stromsam

This is not an error, it's a correct Unicode string escape. You're far more likely to get a real encoding error writing a Java String to a stream. — kdgregory

There are a few bits of info which will make this a more useful question. firstly which JSON library are you using? are you using this in a standalone app or as part of a Java web-app?

if you are using the org.json.JSONObject.JSONObject() then what you have written should work.

The library org.json is available here json.org

running the below code with the suggested library :

JSONObject json = new JSONObject();
json.put("Name", "Müller");
System.out.println(json.toString());

produces :

{"Name":"Müller"}

seems to be what you want

hope that helps

thanks a lot! I used json-rpc-1.0.jar. With the libary from json.org it works the way I wanted.
