File name encode while unzip files

[vivimo]

Hello

I have a little bit problem. When I upload files one by one and in file names are polish characters, everything is ok. But when I upload files in zip archive, server extract them without polish characters.

Any idea how to solve that?

Server is:
OpenKM 5.1.9
Windows 2008 Server
MySQL 5.5

Best Regards

ZIP archive format originally does not support UTF-8 encoding for file names. So depending on the program used, it write file names in different encoding formats. Please, attach a ZIP archive to test in my local installation.

Here you go. I used 7-zip.

Thank You very much for interesting. It's very important for me.

I have created a sample.zip using 7zip 9.20 from a Windows 7, using Cyrillic characters in filename and works fine. ZIP archive uploaded to the demo server and exploded.

As I can see, Cyrilic works but I use Latin alphabet with polish characters like ąśźćż ect. We figure out that OpenKM use old zip library without UTF-8, but since 2007 zip standard can official handle UTF-8 encode in filenames. Why is that?

I have imported this zip in the demo and works fine. This one contains files with Cyrilic and Polish characters.

WOW, whot did You use? 7zip? In my instalation also your archive works but mine not.

There is something wrong. When I upload your sample.zip it looks great but when I download it on my local computer, extract and again add to archive, polish characters doesn't came up. What the f...? I use 7-zip 9.20 x64 and Win 7 x64.
