Prepare this file:

$ cat /tmp/E-7.el
(insert (make-char 'greek-iso8859-7 164))

Start Emacs in UTF-8 locale:

LC_ALL=en_US.UTF-8 emacs -Q /tmp/E-7.el 

In Emacs: `M->', `C-x C-e', `C-x C-s'.  I get:

Expected behavior: Save the file in utf-8.

The same happens with the Emacs_22 branch.  I suppose it would work in
unicode-2, so its not too important for the trunk.  Is their a way to
make it work on Emacs 22 as well?

Thank you for the report.  I think it's a bug of
find_safe_codings in coding.c.  I'm now checking what is
wrong.

I found that this is because unicode mapping in
ucs-tables.el for iso-88590-7 was not up to date.  I've just
installed a fix.  Please try again.

It is fixed, thanks.  I have (tested and) installed the patch in the
Emacs_22 branch as well.

Bye, Reiner.
