> Extra field data can be stored in two places inside a zip archive - the entries local
file data and its central directory entry.
> Currently ZipFile - like* - ignores the data stored inside the central
directory and assumes all information can be taken from the local file data part.
> Unfortunately there are cases where an archiver uses different data, or even worse, only
uses the central directory.  One such case comes up with SANDBOX-176 and WinZIP.  WinZIP uses
InfoZIP extra fields to store Unicode versions of file names but it only stores them inside
the central directory, where ZipFile doesn't look for them.
