Monospaced ascii editor

Question

Is there any ASCII "builder" / "text editor" or anything for that matter that will allow someone to write text differently then a normal text editor. The idea is that you take a monospaced font and fill in a textarea of some sort with all spaces and when you put your cursor anywhere on the text-area it "sticks". The next idea is that whenever you write a character it "eats" or replaces the existing character in that space. I can build this out in javascript fairly easily but I feel like it is a feature of some text editor out there. What are my options? Does this exist?

I hate when this happens when I don't want it to.

Rather then this...

|                      s                 |
|                                \/      |

TheDraw is an old dos application wich does what you need.

I see on the Net more recent alternatives for windows, like AcidDraw and PabloDraw, but I do not know them.

Hope one of them is still useful.
