Comment 28 for bug 580961

The infozip team have recently spoken regarding the current state of unicode and unzip(most specifically the lack of the -O option)

They are preparing another release(6.1) and there is a thread discussing a potential fix for this matter[1]
I'm not sure if the libnatspec based patch could be a candidate for their release, but I lack the proper knowledge to contribute to the discussion there.
@Rolf: If you have not already, could you take a look at the thread?
