I see. This is my problem... suppose I have an environment based on an utf-8
locale, and I want to edit a LaTeX file with jed. Unfortunately, LaTeX does
not understand utf-8 (yet... and I suspect it's quite a complex thing to
implement(*)). So the .tex file should stay on disk as a latin-1 (or latin-9,
whatever) file. But if I am editing it, and type "¡", I imagine that ---
being the locale utf-8 --- jed would see the string 0xC2 0xA1. And put that
into the buffer. Now the problem is --- when writing the file to disk, this
should be written as 0xA1. If I have understood well, this is just the
designed behavior, so that it's fine --- I think.

(*) yes, I know there is Omega and Lambda. But I am not so sure about them...
