    I think this is the wrong thing to do.  As rms said, it's a
    user-visible change that affects more than Ispell.  It breaks the
    principle that Emacs tries to avoid losing information in coding
    conversions (whereas XEmacs readily trashes data).

It would do that if users explicitly specify these coding systems by
name and if Emacs fails, when they subsequently save the file, to warn
that it can't handle all the characters.

Emacs normally does warn when the coding system doesn't handle all the
characters in the file.  Is there a common scenario where that warning
is bypassed?
