Steps to reproduce

1. Create a ZIP file with a file named Files/⚾ (i.e. "Files/\u26BE").
2. Read the ZIP file with DotNetZip.
3. Get the entry and inspect the IsDirectory property.

Example code

using (var zip = new ZipFile("test.zip", Encoding.UTF8))
{
    zip.AddEntry("Files/\u26BE", new byte[0]);
    zip.Save();
}

using (var zip = ZipFile.Read("test.zip"))
{
    ZipEntry entry = zip["Files/\u26BE"];
    Console.WriteLine("IsDirectory: " + entry.IsDirectory);
}

Expected behavior

The IsDirectory property is false.

Actual behavior

The IsDirectory property is true.
