如何在Android上的磁盘上读写UTF-8？

非常简单明了。:)

String filePath = "/sdcard/utf8_file.txt";String UTF8 = "utf8";int BUFFER_SIZE = 8192;BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(filePath), UTF8),BUFFER_SIZE);BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(filePath), UTF8),BUFFER_SIZE);
