Once again, exactly the same arguments that I have already discussed at
least twice.

Not true. The application can control the selected encoding, that is a core
feature of the code.

Since you realize that, please stop waving it around at every occasion.

I already wrote that I will not object to someone implementing this kind of
method as an optional feature.

That is already what my code propose.

Not true.

I use it.

Obviously, Vim is limited to what the terminal can print. How is it

Repeating it will not make it true.
