no results when using unpack with Charset

[yummish]

We have many zips encoded with GBK or GB1314, etc. When I use unpack(inputstream, target, charsetName..), the result is empty and there is exception thrown.

If I don't specify the charset, then it's saying it's malformed.

Well, the process was:

1. Download file to local
2. Get file inputstream
3. pass to unpack

I tried to pass the file directly and it works:

1. Download the file to local
2. pass file to unpack

So if you use byte[] bytes = ZipUtil.unpack(new File("/tmp/demo.zip"), "foo.txt", Charset.forName("yourCharset")); it works but when you open the InputStream yourself and call ZipUtil.unpack(InputStream is, File outputDir) it fails?

Do you open the InputStream with the correct encoding? Can you share the code that works and the code which doesn't? And if you feel this is a zt-zip issue can you provide with an archive to test with?
