Arch Linux

Description:
Non-english world (CJK characters) *really* need this patch because currently there are no other utilities properly handle this issue and there are plenty of this kind of zips (almost all in those containing non-ascii file names).

Note: unzip 6.0-4 has this patch included, while the patch is removed from unzip 6.0-5 with a reason "upstream doesn't include this patch". upstream unzip team rejected the iconv patch long before and people do need this patch, in fact unzip 5.x in major dists (include arch) include this patch.

Note that the saying "unzip does not support UTF-8 filenames" is not accurate. unzip does support utf-8 zips created from linux world. However, zips created from linux are usually not utf-8 encoded.

Additional info:
* package version(s)
unzip 6.0-5


Steps to reproduce:
For a zip file created from non-english Windows world which contains non-utf8 non-english file names.
Unzip it, file names are not readable, or may fail due to invalid filename.

For exmaple, "tankrule.zip" from http://astardata.baidu.com/download/tankrule.zip:

% unzip tankrule.zip
Archive: tankrule.zip
inflating: Astar2010��+-��i��ۤ����=.pdf
% ls
Astar2010??+-??i??ۤ????=.pdf

If I use a version with iconv patch, say, unzip 6.0-4, I can use -O option to correctly extract this file:

% unzip -O GBK ./tankrule.zip
Archive: ./tankrule.zip
inflating: Astar2010坦克大战详细规则.pdf
% ls
Astar2010坦克大战详细规则.pdf

Recommended solution:
Reuse unzip 6.0-4 PKGBUILD and that's all.
