Yes, it's better for Emacs, but not for the other programs
(e.g. ispell).  And such Emacs Lisp applications that use
wrong coding system should be fixed anyway.

I was also thinking about that for emacs-unicode.  Perhaps
using the same format as yudit is good.   And, we'll provide
a command `recover-unencoded-characters'.

For instance, the MIME charset iso-8859-1 can encode Latin-1
chars only, and it's stateless, no escape sequences.
