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
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"
b1=[ 0xc3, 0x83, 0xc2, 0x81, 0xc3, 0x83, 0xc2, 0x89, 0xc3, 0x85, 0xc4,
0xb0 ] (incorrect)
Here is an another test:
String s2="ÁÉŰ";
Window.alert(s2);
byte[] b2=s2.getBytes();
The results:
Alert: "ÁÉÜ" (correct)
s2="ÁÉÜ" (correct)
b2=[ 0xc3, 0x81, 0xc3, 0x89, 0xc5, 0xb0 ] (correct, same as in
"response" string above)
I think, the JSONParser.parseStrict or
JSONObject.get().isString().stringValue() can't handle correctly the UTF-8
characters...
Any idea? :(:(:(:(
Additional information:
The request and response Content-Type is "application/json; charset=UTF-8".
Source code files and the development environment use UTF-8. The HTML page
in browser encoding also UTF-8.
I have problem only with the response only. The request character
coding/encoding is correct.
Thank you for any help,
Tibor
