I have a task, to parse a simple JSONs. I store my JSONs in a String variable. A JSON can look like this:

 String json = "{n" +
                "    "DateFrom": "2023-10-11",n" +
                "    "DateTo": "2023-10-23",n" +
                "    "SpatioTemporalDatabase": "ArsoMeteo.db",n" +
                "    "DeviceName": "MURSKA SOBOTA - RAKIČAN",n" +
                "    "DatastreamList": ["mean T", "mean rel. hum.", "precipitation"],n" +
                "    "TargetColumnList": ["Temperature", "Humidity", "Rain Rate"],n" +
                "    "AggregationMethodList": ["Mean", "Mean", "Sum"],n" +
                "    "TimeResolution": "Hour"n" +
                "}";

Now what I want to do is to parse the json like that: StringEntity entity = new StringEntity(json); . When I do this though, I get this error:

ON request getFiles() Exception {"errorMessage":"Unspecified errorrn"}

I know I can do this json = json.replace("Č", "\u010C"); and it can solve my problem, however there many other characters Ç. I want to encode this character but I don’t know how.. Any suggestion? The language I use if it help is serbian.

Thank you in advance
