Windows 7 How to convert odd filenames into cyrillic/russian filenames?

[pstein]

I have got a *.zip file which contains some files with original filenames in cyrillic/russian font/letters.

However when I look at them in WinExplorer on an english Win7 then the filenames appear very odd, something like:

üá½áíá¼á ìáñ¿´.txt

How can I convert them into cyrillic/russian font chars codepage based filenames (which are readable here)?

Thanks
Peter
