I can reproduce it with your config, when I use libc with limited locale
support. On "big" config with glibc, I can't.

Yes. This is the test that libc locale subsystem understood byte sequence 0xce,
0x94 as one Unicode character. If it didn't (width != 1), then we conclude that
current locale (as set by $LANG) is not Unicode, and turn Unicode support off:

unicode_status = (width == 1 ? UNICODE_ON : UNICODE_OFF);

and from that point on, any chars with high byte set will be treated as

Either set $LANG properly (say, to "en_US.utf8") and/or make sure your libc
does support Unicode, or unset CONFIG_UNICODE_USING_LOCALE in the .config - I
unset it and now it works for me:

$ ./busybox ls /.2/video_rus/*_11.avi
