Re: Saving when the coding system can't code all buffer characters

[Richard Stallman]

    I think it is important to have a simple way to find the problematic 
    character too. As I wrote before something like a button field in the 
    *Warning* buffer is one idea.

That has two drawbacks:

* It requires you to click on a button.

* It won't work on a tty at all.

The suggestion to put this into straight into that buffer,
and not require the user to type or click anything, is much better.
Would someone please implement that so we can try it?
