#620 Unicode filenames not supported in zip archive creation
If you try to create an archive containing the file
called "β.txt" it is OK.
But with "œ.txt", it becomes "o.txt"
But with "ۍ.txt", it becomes "?.txt"
The three characters are non-ascii, but are managed
differently.
But it is working properly using 7z format (if I could
use only this format...)
I'm using 7-Zip 4.42 under Windows XP, French version.
Please find attached some zip samples

A year (or two or three?) ago I ran into this, and had to
give up on WinZip and WinAce both, and go to 7-zip for any
uses involving files with unicode names.
I assumed it was a problem with the protocol they use (which
would not really be fixable by 7-zip, except by using a
different protocol).

in fact, as you can see here :

Zip specification doesn't specify how non-ascii characters
must be managed. Despite that, on a same computer, you
should be able to extract what you have archived. I have
downaloaded last trial version of WinZip (10.0), and it's
not working either...

In fact it's working with Winzip.
I had tried to zip with WinZip then Unzip with 7-Zip : this
is not woorking, but zipping and unzipping with WinZip works
fine.
The latest ZIP format specification supports Unicode file names. Names must be encoded in UTF-8, and the 11th bit in the general purpose flags field (2 bytes at offset 6) must be set.
