 I can write my own text editor on top of Posix easily enough.
But I want to implent an "edit" command so that users can edit files.

Just make the editor a part of the shell.

And you just can't edit files without non-ASCII keys.

I have edited files without non-ASCII keys so I know it can be done.
However, non-ASCII keys make it easier, especially if the files contain
non-ASCII characters.

So at the moment I call system with nano, and it wotks. But it's a clunky solution.
