Subject: 25.1.50; wrong saving of unicode characters into kill ring
Date: Fri, 27 May 2016 08:57:22 +0200

Hi,

When inserting "€" in a buffer, killing it, than reinserting (yank) it,
I get "?" instead of "€".

This is needed for reproducing:

1.) Call "LC_ALL=en_GB.utf8 emacs -Q"

2.) Evaluate the following line:

    (setq select-active-regions nil)

3.) Type "€"

4.) Kill the "€" (select it and than C-w)

5.) C-y

Configured features:
XPM JPEG TIFF GIF PNG RSVG IMAGEMAGICK SOUND DBUS GSETTINGS NOTIFY
GNUTLS LIBXML2 FREETYPE XFT ZLIB TOOLKIT_SCROLL_BARS GTK2 X11

Important settings:
  value of $LC_ALL: en_GB.utf8
  value of $LC_CTYPE: en_GB.utf8
  value of $XMODIFIERS: @im=local
  locale-coding-system: utf-8-unix

Major mode: Lisp Interaction

TIA for investigation,
-- 
           Peter

Not reproducible on my system.  (Btw, you omitted the details about
your OS and build.)

How did you type "€", and what does Emacs say when you type "C-u C-x ="
with the cursor on that character?

Thanks.

Sorry, by mistake I killed too much...

"Alt Gr + e" because I have this line in my .Xmodmap:
keycode  26 = e E EuroSign EuroSign EuroSign EuroSign

But "M-x insert-char" and then "euro sign" works too.

Strange.  Do you have some clipboard-related agent active that tries
to do something with stuff pasted from the clipboard?  What happens if
you set interprogram-paste-function to always return nil?

Oh, one more question: what is the value of selection-coding-system?

xcb is running. (no problem since 1995...)

I've killed it, but that does not change anything.

Indeed, this solves the problem. But it's no more possible to insert
text from other programs with C-y.

I've found another one: vncviewer

The copy-paste-problem happens only, when at least one vncviewer is
running.

After further investigation, copy-paste in xterm has the same problem,
that means, that this is not (or not only) an emacs-bug.

I'll report it to the vncviewer list.

Sorry about the needless bug-report.

Right, as expected.

Strange, AFAIR Emacs is not supposed to get text from the clipboard if
the text there came from the same Emacs session.  It should take the
text from the kill-ring.
