如何解压缩具有 unicode 文件名的 zip 文件？这是我的代码：

try {
    ZipInputStream zis = new ZipInputStream(
            new FileInputStream(zipFile));
    ZipEntry ze = zis.getNextEntry();

    System.setProperty("file.encoding", "UTF-8");
    while (ze != null) {
        String fileName = new String(ze.getName().getBytes("UTF-8"));
        System.out.println(fileName);
        File newFile = new File(outputFolder + File.separator + fileName );

        BufferedOutputStream outStream = new BufferedOutputStream(new FileOutputStream(newFile));
        OutputStreamWriter osw = new OutputStreamWriter(outStream, Charset.forName("UTF-8"));
        int ch;
        StringBuffer buffer1 = new StringBuffer();
        while ((ch = zis.read()) > -1) {
            buffer1.append((char) ch);
        }
        osw.write(buffer1.toString());
        osw.close();
        outStream.close();

        ze = zis.getNextEntry();
    }

    zis.closeEntry();
    zis.close();
} catch (IOException ex) {
    ex.printStackTrace();
}

但我收到错误UTFDataFormatException：：

06-05 08:46:33.394: W/System.err(777): java.io.UTFDataFormatException: bad second or third byte at 6 
06-05 08:46:33.394: W/System.err(777): at java.nio.charset.ModifiedUtf8.decode(ModifiedUtf8.java:56)

我的课是ZipManager。

如何解决这个问题？

根据异常，您的文件似乎实际上不在UTF-8编码中。

此外，问题不在于文件名。这一行：

 String fileName = new String(ze.getName().getBytes("UTF-8"));

是没有意义的，因为ze.getName()已经是正确的java字符串了。
