测试代码如下：
java 代码
1. public class Test {
2.
3. static String IN_PATH = "F:/Novel";
4. static String OUT_PATH = "F:/NovelConvert";
5.
6. public static void main(String[] args) throws Exception {
7. Converter convert = new Converter(IN_PATH, OUT_PATH, "Unicode");
8. convert.convert();
9. }
10. }
程序是可以正常执行了，并且也转码了，不过不幸的是转成后的文件格式不是unicode，而是unicode big endian，拷贝到手机里还是乱码，nnd，现在也不管手机可否看了，我想问大家一下，如何修改才可以把txt文件改成unicode格式呢？
