Java 解決BufferedReader讀取UTF-8文件中文亂碼

（侵刪）

讀取txt文件亂碼：
BufferedReader read = new BufferedReader(new FileReader(new File(filename)));

解決辦法：
InputStreamReader isr = new InputStreamReader(new FileInputStream(file), "UTF-8");
BufferedReader read = new BufferedReader(isr);

因為InputStreamReader和BufferedReader都繼承自Reader,而BufferedReader的構造器又是Reader.
