I've just tested that the problem occurs also in CVS Emacs, so I
cross-post to emacs-devel.

When I paste two kanji characters from Mozilla (Debian package 1.4-4)
to Emacs 21.3.1. from the Debian package or to the CVS version
compiled by myself (21.3.50.1), I get

\x{65E5}\x{672C}

The numbers in braces are the correct Unicode code points of the
characters in question.

I repeated the experiment in a different Debian installation. When I
paste from Galeon 1.2.5 to Emacs 21.2.1 from the Debian package, I get
just 2 question marks. However, when I paste them into exactly the
same CVS version as above, I get two strange characters (displayed as
question signs in reverse video), the first one being reported as "c
with acute":

------------------------------------------------------------------------
  character: ć (0346, 230, 0xe6, U+65E5)
    charset: eight-bit-graphic (8-bit graphic char (0xA0..0xFF))
 code point: 230
     syntax:   	which means: whitespace
buffer code: 0xE6
  file code: not encodable by coding system iso-8859-2
       font: -ETL-Fixed-Medium-R-Normal--16-160-72-72-C-80-ISO8859-1

Composed with the following character(s) `—¥' to form `æ—¥'.

There are text properties here:
  fontified            t
  untranslated-utf-8   26085
  composition          (0 3
   [326333])
-----------------------------------------------------------------------

The Unicode code point is correct, but the rest seems a complete mess
:-(.

Las but not least, a good news: the characters are pasted correctly in
unicode-emacs.

Best regards

Janusz

Did you have `utf-translate-cjk-mode' turned on?  (do M-x ...)

Cut-n-past of japanese characters between Mozilla and (CVS) emacs works
perfectly for me if I do that.

Thanks, cut and paste works OK with `utf-translate-cjk-mode' on.

However, with its default value Emacs should behave in a more
reasonable way than that described in my previous posting.

I believe it is a TODO item to automatically load the CJK-UTF 
translation tables when they are needed. If you have time, you could 
have a go at implementing that. Otherwise I find it hard to see what 
Emacs could do that is more reasonable than it does now (refuse to paste?).

IMHO refusing to paste (with some explanatory message) is much better
than inserting rubbish.
