The following code shows Zip File System Provider does NOT respect the "language encoding flag".

zos.close();

Paths.get("test.zip").deleteIfExists();
File f = new File("test.zip");
FileOutputStream fos = new FileOutputStream(f);
baos.writeTo(fos);
fos.close();

// Read back with Zip FS - utf8
out.println("Read back with Zip FS - utf8");
Map<String, Object> env = new HashMap<String, Object>();
Path file = Paths.get("test.zip");
ZipFileSystem fs = (ZipFileSystem) FileSystems.newFileSystem(file, env,
null);
System.out.println(fs.getPath(name).exists());
fs.close();

// Read back with Zip FS - gb2312
out.println("Read back with Zip FS - gb2312");

env.put("encoding", "gb2312");
file = Paths.get("test.zip");
fs = (ZipFileSystem) FileSystems.newFileSystem(file, env,

fs.close();
}

}

The source code of ZipPath shows the root cause:
@Override
    public boolean exists() {
        if (path.length == 1 && path[0] == '/')
            return true;
        try {
            return zfs.exists(getResolvedPath());
        } catch (IOException x) {}
        return false;
    }

 // resolved path for locating zip entry inside the zip file,
    // the result path does not contain ./ and .. components
    private volatile byte[] resolved = null;
    byte[] getResolvedPath() {
        byte[] r = resolved;
        if (r == null) {
            if (isAbsolute())
                r = getResolved();
            else
                r = toAbsolutePath().getResolvedPath();
            if (r[0] == '/')
                r = Arrays.copyOfRange(r, 1, r.length);
            resolved = r;
        }
        return resolved;
    }

==========================
From the above code, we can not see "language encoding flag" check. We can not even see a Coder or something alike.

And I think the issue may not only exist in method exists(). It should exist in other methods.
