    What you mean is that Emacs is asked to _select_ or to _verify_ a coding
    system (as is customary for interactive editing of a file) it will do so
    and get back to the user when necessary.

    But that is _quite_ different from Emacs being _incapable_ of encoding
    raw bytes to a file or a stream of a specified encoding.  It means that
    when you are using an _application_ that is expected to deliver only
    decodable characters, then the _application_ will _ask_ before going

    But the _engine_ is perfectly capable of going through here.

I think that both of these are points correct.  But there is still the
question of what the engine should do by default.

We can set the defaults for those non-frile interfaces so as to reject
invalid UTF-8 sequences.  Then a program could specify to override the
default and allow them.
