I suggested doing that, but I realize now that this isn't easy.  The
*Warning* buffer shows several characters for each encoding that is
unsafe, like this:

    However, each of them encountered characters it couldn't encode:
      cp1251-unix cannot encode these: x x x x x x x x x ...
      iso-latin-1-unix cannot encode these: y y y y y y y y y ...

Each one of `x' and `y' is a different character, potentially from
several different character sets.  How to display information about
them based on what "C-u C-x =" produces?
