Thank you for the bug report.

It seems that bug affects not only column-number-mode, but
the more basic functions current-column and move-to-column.

For instance, in the function current_column_1 (indent.c),
we now have these codes at line 632:
      scan++;
      scan_byte++;

Here, we must add the length of the current multibyte form
to scan_byte instead of just incrementing it.

Fmove_to_column has the same problem.
