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

[Richard Stallman]

Handa-san, would you please join in this?

    The first problematic character is at point in the displayed buffer,
    and C-u C-x = will give information about it.

    At the prompt "Select coding system (default mule-utf-8):" this just 
    gives information about the minibuffer.

That is true.  So you have to switch windows in order to use the command
C-u C-x = to get that information.

     And when using C-g to quit the 
    problematic character disappears from screen.

Of course, that is what C-g is supposed to do.

I see two things we could do:

* Change the message to say that you need to switch to that window
before you give the command.

* Make up some simpler command, and make it work without switching
  windows.  What command could it be?  It has to be typable on a tty.
