Description
Now, Trac generates a zip file while downloading as zip in changeset and all attachments files as zip (0.13+). The filename of the zip file is encoded with utf-8. but "Language encoding flag" in zipinfo.flag_bits is unset.
If the bit is set, 7-zip extracts as unicode in Windows. If unset, it extracts broken filename. (confirmed on Windows XP.)
However, even if set, zip folder in Windows XP and 7 extracts broken filename.

Committed in [11043/branches/0.12-stable] and [11044/trunk].
So I suppose this would fix #4432?
I think that it should keep open, because Zip folder in Windows cannot handle the bit.
I think that Windows users need "encoding for zip archive" option in trac.ini and user preference.

We missed that convention when we talked about which encoding to use. Nice! So I suppose this would fix #4432?
