Thanks, I didn't know about recode.  But it doesn't work all that well:
c{\c c}c does not remove braces, for instance, and what's even worse, it
apparently doesn't know about \k.

But thanks anyway, this is a good thing to remember, even though in my
case I perceive it as even more hackish than my approach (I'd prefer
Emacs to do the job, not an external utility).

Best,
