This change will do.

Or, if this is a problem only for ispell, we can make series
of "safe" coding-systems for ispell.

Or, we can add a global flag, say
`inhibit-unsafe-iso-escape, to tell encoding routine not to
produces those escape sequences.  Then, ispell can let-bind
that variable to t on encoding.

I think the last one is the best solution.

What do you think?
