This is terminal issue, not related to coreutils at all.

Have a look at this transcript:
$ cat |od -a
абв
0000000   P   0   P   1   P   2  nl
0000007
$ cat |od -a
абг<backspace>в
0000000   P   0   P   1   P   P   2  nl
0000010
$ cat |od -a
абг<backspace><backspace>в
0000000   P   0   P   1   P   2  nl
0000007

When you hit backspace, your terminal driver erases only last byte of the
two-byte symbol 'в'.
