7-zip and archives that contains files with non-English file names

after reading this in the 7-Zip revision history:

- Unicode (UTF-8) support for filenames in .ZIP archives. Now there are 3 modes:
1) Default mode: 7-Zip uses UTF-8, if the local code page doesn't contain required symbols.
2) -mcu switch: 7-Zip uses UTF-8, if there are non-ASCII symbols.
3) -mcl switch: 7-Zip uses local code page.

I change the link 7-Zip File Manager to use -mcu.

Things now work much better.
