解決BufferedReader读取UTF-8文件中文乱码

解決BufferedReader读取UTF-8文件中文乱码
读取txt文件乱码
【Java代码】
　　BufferedReader read = new BufferedReader(new FileReader(new File(filename)));
解决办法：
【Java代码】
　　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.
Writer也是一样的处理
【Java代码】
　　FileOutputStream writerStream = new FileOutputStream(filePath, true);
　　BufferedWriter oWriter = new BufferedWriter(new OutputStreamWriter(writerStream, "UTF-8"));
