GSON not sending in UTF-8

Question

The following method sends a JSON reply. However on the receiving end I keep getting invalid characters, and UTF-8 isn\'t decoding the data. What am I doing wrong?

Answer 1

I have no idea why you would write your own HTTP protocol code. It's a lot like writing your own XML parser: No matter how good a programmer you are, you are bound to get it wrong.

Anyway, as the DataOutputStream documentation states, doing writeBytes on a String will just discard its high eight bits. So what you get is... something, but not UTF8. What you should do is:

String jsonString = new Gson().toJson(objectToEncode);
byte[] utf8JsonString = jsonString.getBytes("UTF8");
responseToClient.write(utf8JsonString, 0, utf8JsonString.Length);
