nothing works as need.

imagine only two test characters as "O" and ":" in the center.
position "O" somewhere near ":" but not over it initially.

implement consistent to ascii borders logic that switch the state of overlapping character to overlayer and will allow to jump over it at the same coord by preserving both characters in the same coords.

then switch both characters to overlayer mode if they met at the same coord so they can actually consistently overlap onto each-another but in the same coord.

then think which what is rendered when and how it need to be rendered or excluded/added from ascii matrix properly on overlap or overlay.
