Hi, my stack is overflow :):):):) I can't find the solution...
I'm developing a server-client application.
My GWT client running in browser. Communicate with my C++ server by:
GWT-JSON -> lighttpd -> libfcgi -> cgicc -> libjson -> C++ application
My problem:
The server response with a JSON string to client's request. This response
contains UTF-8
strings. Accent characters encoded correctly with "\uXXXX" in response. For example:
"Á"
encoded: "\u00C3\u0081".
The client extract the string from JSON string. But the extracted string
contains bad
encoded characters. :(:(:(:(
Lucky, I can narrow the problem to JSON-GWT. Here is a code to demonstrate the
problem,
running in client side only in GWT:
String response="{ \"test\" : \"\\u00C3\\u0081\\u00C3\\u0089\\u00C5\\u00B0\"
}";
//"ÁÉÜ" in UTF-8
No. That's not UTF-8, that's UNC encoding. It results in Java's UTF-16 encoding.
JSONObject json=JSONParser.parseStrict(response).isObject();
String s1=json.get("test").isString().stringValue();
Window.alert(s1);
byte[] b1=s1.getBytes();
The results:
Alert is: "à ÉŰ" instead of "ÁÉÜ"
s1="à ÉŰ" instead of "ÁÉÜ"
That's the correct UTF-8 encoding of your characters.
It is working as intended. Perhaps you should read a bit more about Unicode, UTF-8, UTF-16
and all this confusing stuff... :-)
