The "Local Variables" section has been created successfully, but the
names of the coding systems are wrong.  Below[1] is a patch against
CVS HEAD (but only tested with texinfo-4.6 sources, because my
autoconf apparently isn't new enough to bootstrap CVS HEAD).

Maybe Emacs ignores unknown codings in local variables, so it was
`accidentally correct' here. ;-)

If you're using the X11 version (not emacs -nw) you can use:

$ LC_ALL=greek emacs -no-site-file -q -f info

(info)Top will display "7" (7 -- greek-iso-8bit (alias: iso-8859-7))
in the mode line.  When entering a iso-8859-1 node, it should change
to "1" and display e.g. ÄÖÜäöü (AOUaou with diaeresis) correctly.
Else you will see e.g. "Delta" instead of @"A and "phi" instead of @"o
(see the sample file[2] below).

Bye, Reiner.
