Question

目前，我正在使用gson来对对象执行序列化。它在单一平台（Windows）中工作得非常好。

但是，如果我要在不同平台（Windows，Linux，Mac，Android）上共享json文件，我是否需要使用特定类型的编码（UTF-8）？（json文件中会有外语字符）？或者，BufferedWriter / BufferedReader使用的默认编码在所有平台上都是相同的？

public static boolean write(A a, File file) {
    final Gson gson = new Gson();
    String string = gson.toJson(a); 

    try {
        //If the constructor throws an exception, the finally block will NOT execute
        BufferedWriter writer = new BufferedWriter(new FileWriter(file));
        try {
            writer.write(string);
        } finally {
            //no need to check for null
            //any exceptions thrown here will be caught by 
            //the outer catch block
            writer.close();
        }
    } catch (IOException ex){
        return false;
    }
    return true;
}

public static A load(File file) {
    // Copy n paste from newInstance.
    final Gson gson = new Gson();

    try {
        //If the constructor throws an exception, the finally block will NOT execute
        BufferedReader reader = new BufferedReader(new FileReader(file));
        try {
            return gson.fromJson(reader, A.class);
        } finally {
            //no need to check for null
            //any exceptions thrown here will be caught by 
            //the outer catch block
            reader.close();
        }
    } catch (IOException ex){
    }
    return null;
}

只是添加它，FileReader和FileWriter是特定于平台的。更喜欢ObjectStreams。同样，我的分数不允许我把它作为评论:(

如果JSON文件将在不同平台上共享，我是否需要关心编码类型？
