I can't see how this is a meta-vs-ISO8859-1 issue. It was because in
old text-type terminals, this (setting the 8th bit) was just how the
Meta key used to work. In the old days ISO8859-1 was not even the
standard.
I would personally agree that Alt *ought* to be an alternate character
set key. Except that it was not in DOS, nor in Windows.
