Subject: 24.0.50; Problems with Multi_Key
Date: Tue, 04 May 2010 22:41:01 +0200 (CEST)

Of all applications I know on my computer, emacs is the only one which
doesn't accept multi-key compositions.  Calling `emacs -Q' and
pressing the composite key (which I've mapped to the `Windows menu'
key), I get

  <Multi_key> is undefined

and the composition isn't performed.  This behaviour wasn't present in
previous versions of Emacs (about a half year earlier, I estimate).
Note, however, that I'm now using Xorg 1.8.0 (from openSuSE factory),
together with fairly recent versions of all other Xorg modules, so the
problem might be elsewhere.

As pointed out in my last mail to emacs-devel, this might be the problem
(seems to be for me, anyway): try with '@im=none' (e.g. starting
Emacs with 'env XMODIFIERS="@im=none" emacs'.

Indeed, this circumvents the problem.  Thanks!  Anyway, it looks like
a bug somewhere since this action wasn't necessary previously, and
Emacs worked fine with scim too.

How did you remap it?  What is the output of xev if you press the keys
<Multi_key> <a> <e> in this order?

Unchanged since years; I have this line in xorg.conf:

Subject: Problems with multi key on 23.2.1
Date: Tue, 15 Feb 2011 14:57:21 +0100

Hi!

I've just found this bug report.

I also have problems with multi_key.
I define the Multi_key with xmodmap, using:
keycode 115 = Multi_key

This works fine in most programs, even emacs when I start it in text
mode (inside an xterm).

However, when I start it as X application and press the key, I get
<Multi_key> is undefined
in the status bar.

I'm using the X version that's coming with NetBSD/5.99.45.

For me, 'env XMODIFIERS="@im=none" emacs' doesn't work, I still get
the same error.

"unset LC_CTYPE; emacs" doesn't work either.

Here's the emacs-bug-report info:

dear maintainers,

I would also like to report this bug. Here are some considerations
about emacs, input methods, and compose key (and the compose file
.XCompose):

1) Starting Emacs with 'env XMODIFIERS="@im=none" emacs' is not a
clean solution.
2) A user should not be forced to choose between the input method and
the compose key.
3) Some input methods (e.g. ibus, uim) can work with the compose key.
4) Other programs can work both with input methods and the compose key.

E.g. in my case, I use some japanese/chinese characters together with
composed latin characters like "ç" or "ś". I hope emacs implements
this functionality so that users can produce "universal" text files
more easily.

Yul
