Problem with Volume label.

I have a problem with Finder in OS X Lion.

When i use volumes with Cyrillic chars and spaces (label name like "Мой диск"), Finder incorrect work with it. I can't use item with this element in left side of Finder window. If i change current location for Computer, i see this volume. Then i open it and i can't open files there (system can't determine file formats but i can correct open this files with programs menu). If i try copy it, i get error message with "error 8060".

I think that it's problem with Cyrillic symbols or spaces in Finder because when i try copy this files in Terminal and "cp" command, i success copy its.

Help me fix it, please.
