用 java 将文件的编码从GBK 转换成 UTF8

非常好，解决了我的一个大问题。真是感谢。代码生成的java和jsp终于不再手工转码了。

核心代码：

private static void transferFile(String srcFileName, String destFileName) throws IOException {
String line_separator = System.getProperty("line.separator");
FileInputStream fis = new FileInputStream(srcFileName);
StringBuffer content = new StringBuffer();
DataInputStream in = new DataInputStream(fis);
BufferedReader d = new BufferedReader(new InputStreamReader(in, "GBK"));// , "UTF-8"
String line = null;
while ((line = d.readLine()) != null)
content.append(line + line_separator);
d.close();
in.close();
fis.close();

Writer ow = new OutputStreamWriter(new FileOutputStream(destFileName), "utf-8");
ow.write(content.toString());
ow.close();
}

将一个GBK编码的文件转成UTF8　编码的文件
