Thanks Daniel for your response,
In my app, the user enters a name in japanese language which is to be
sent to server in a JSON request.The server expects the name parameter
in form of a UTF-8 encoded string.
So the encoding of source code should not matter.Here is the sample code
public static String EncodeJson(String strJson)
{
try
{
String strHex = null;
for (int i = 0; i < strJson.length(); i++)
{
try{
//char c = strJson.charAt(i);
// int j = (int) c;
// System.out.println("ASCII OF "+c +" = " + j + ".");
//System.out.println("strJson.charAt(i), 10=
"+Integer.parseInt(""+strJson.charAt(i), 10));
if ( strJson.charAt(i) >= 126)
{
String start = strJson.substring(0, i);
String end = strJson.substring(i + 1);
int jsonChar = strJson.charAt(i); // new
string(strJson[i], 1);
strHex = "000" + Integer.toHexString(jsonChar);
strHex = strHex.toUpperCase();
strJson = start + "\\u" +
strHex.substring(strHex.length()-4)+ end;
i += 5;
}
}catch(Exception e){
System.out.println(" Exception -
strJson.charAt(i)= "+strJson.charAt(i));
}
}
return strJson;
}
catch (Exception ex)
{
Log.i("Encode", ex.toString());
return strJson;
}
}
The output of this method is passed to JSON object using its put
method.At this point an additional "\" gets added to the parameter
due to which the server does not recognize this as a valid UTF string
Thanks,
Alok.
