Unicode characters displayed as Question Marks in Java JSON Parsing

I have been looking for this over the past few days, but I don’t think I can find the right pointer. Combine it with the appropriate question if it is found as a duplicate.

I am new to working with JSON, and as part of one of my projects I need to decrypt the JSON file and continue processing it. However, when I tried to decode using the Json simple library, I get some weird question marks in the parsed object instead of the actual characters. A sample code is shown below:

String str = "{\"alias\": [\"Evr\u00f3pa\", \"\u05d0\u05d9\u05e8\u05d5\u05e4\"]}";
JSONParser parser = new JSONParser(); 
JSONObject jsonObject = (JSONObject)parser.parse(str);

System.out.println(jsonObject) gives {"alias":["Evrópa","?????"]}

I tried using Json-lib with the same result too.

Thanks for the help.
