Java 解決BufferedReader读取UTF-8文件中文乱码

读取txt文件乱码：
BufferedReader read = new BufferedReader(new FileReader(new File(filename)));

解决办法：
InputStreamReader isr = new InputStreamReader(new FileInputStream(file), "UTF-8");
BufferedReader read = new BufferedReader(isr);

因为InputStreamReader和BufferedReader都继承自Reader,而BufferedReader的构造器又是Reader.
