`C-x 8 a' `ascii' problem fixed

`C-x 8 a' `ascii' problem fixed

[Lars Magne Ingebrigtsen]

RMS sent me this new version of iso-insert.el that fixes the problem
with `C-x 8 a' resulting in an ascii char being inserted.  (Kinda.)

Could the people who have seen these problems install this file and
see whether all those CTE 7bit/CT charset "ascii" problems go away?

(It will be included with Emacs 20.4.)

Re: `C-x 8 a' `ascii' problem fixed

[Jon Kvebaek]

Yup, works for me - or in a fashion. Something is wrong, but that
might just be me ;) Here's what happens:

After a fresh start it works in the scratch buffer - C-x 8 a and an
eval on (char-charset (following-char)) yields latin-iso8859-1. I'm
happy.

The only thing I do in my .emacs with charsets is

(set-language-environment "Latin-1"), and the buffer is indicated with
a -1:

So far so good.

If I then start pgnus, it still works in the scratch buffer. The gnus
buffers are also marked -1:

However, after starting Gnus I have to do a standard-display-european
to turn those pesky \370s and such into sane characters. (See
http://home.sol.no/~jkv/pgnus.gif)

By now, Gnus looks good, but hey:

If I *then* try to eval (char-charset (following-char)) in the scratch
buffer it yields ascii - and the scratch buffer is marked just -:

The same happens in the Gnus buffers that are still marked -1: - a
(char-charset (following-char)) yields ascii on iso-8859-1 characters.

Phew. Did anyone understand this?

Huh.  I don't have to do that...

Yes; doing a standard-display-european makes the *scratch* buffer be
unibyte, which you don't want.  I think.

Lucky you ;) Could you tell me what you *do* do with character/display

combination I can think of (my mind has limits though), and I always
end up with having to use standard-display-european.

Just my thought as well. I don't want that.
