The built-in ZIP function in Windows produces zip files with non-UTF-8 file names. Unzipping them with Ark leads to completely unusable files in KDE. They can not even be deleted or renamed with Dolphin.

Reproducible: Always

Steps to Reproduce:
1. Create a new directory or file with Umlauts in Windows 7
2. Send To: Compressed Folder
3. Move the ZIP file to an UTF-8 KDE System
4. Uncompress with Ark
5. Try to access the files with Dolphin
Actual Results:  
The Umlauts should be preserved. The file should be accessible with Dolphin.

Expected Results:  
The Umlauts are broken. The files are not accessible with Dolphin.

The ARK team can safely ignore the fact that Dolphin is currently so horribly broken that it can't modify files even if ti can display them. It's enough to provide correct interoperability with Standard Windows ZIP files.
