Be careful about the case where the user does:

   > emacs some-file
   C-s foobar
   C-x k RET
   C-x C-c

In such a case, `desktop' won't see the `some-file' buffer since it's
been killed before exiting.

Hmmm... I can't seem to find where this problem was introduced.
Have you ever gotten this functionality to work before
(e.g. in Emacs-21.1) ?

so the day had come and I decided to explore the wonderful world of
Emacs 21 and Mule, what with all the nice Debian packaging of them out
there.

so I installed Emacs 21 and mule-ucs (it seemed like a good idea, or
was it?), and I've put the following into .emacs:

(set-language-environment "Cyrillic-KOI8")      ; I want my cyrillics
(define-coding-system-alias 'mule-utf-8 'utf-8)  ; per mule-ucs README
(set-keyboard-coding-system 'utf-8) ; my keyboard generates
                                    ; Unicode-encoded cyrillic chars

now, I'm mostly interested in making X selection play well between
Emacs and several Unicode-based apps (mainly Mozilla and a couple of
GTK2-based critters).

I had to play with the locale settings, to get the X clipboard to
approach at least some sanity.  so they ended up like this
(considering that I don't want the programs to speak Russian at me and
I live in Israel):

LANG=ru_RU.UTF-8
LC_CTYPE=ru_RU.UTF-8
LC_NUMERIC=he_IL
LC_TIME=he_IL
LC_COLLATE=ru_RU.UTF-8
LC_MONETARY=he_IL
LC_MESSAGES=C
LC_PAPER=C
LC_NAME=C
LC_ADDRESS=he_IL
LC_TELEPHONE=he_IL
LC_MEASUREMENT=he_IL
LC_IDENTIFICATION=ru_RU.UTF-8
LC_ALL=

if I select a chunk of cyrillic text in Emacs and paste it into
Mozilla, all is well.

now, if I select a chunk of cyrillic text in Mozilla and paste it into
Emacs, I do indeed get the same-looking text.  however, the char codes
are different from whatever Emacs itself chooses for the same entities
if I type them into it (which is just weird, but no biggie), and (as a
consequence, probably) the pasted text is shown in a different font
(which is butt ugly).

so basically I'd like Emacs to somehow recognize the cyrillic
characters in the X selection it receives, and to convert them into
the codes it itself uses for the same characters.  how do I do that?

There are few personal problems which can't be solved by the suitable
application of high explosives.

Hi - 

   I've used emacs for years and this seems like a newbie question, but 
I can't figure it out or find it in an FAQ: inserting quote characters, 
and also the forward-slash, in emacs, seems to trigger a 'compose 
character' behavior or something.  When I hit '/' I get, at the bottom 
of my screen:

/[ /234=AEO\aceo]

..if I type one of the characters above then some weird control 
sequence is inserted, otherwise I get the slash character I want.  Same 
thing happens for the " character.  

It seems to only happen in LaTeX mode, and then only sometimes.  I can't 
figure out when or why, and / & " say they're mapped to self-insert-
command and tex-insert-quote, respectively, neither of which should do 
what I'm seeing, AFAICT.  I'm running 23.5 on Mac OS X (from a terminal).

I would really appreciate anyone who can point me to the solution.

Thank you!

I'm not sure if i worked in 21.2, I guess I could try installing it and 
see if the problem persists... I'll check it out when I get time.
Thanks for the help.
