Run Emacs under gdb and set breakpoints at
selection_data_to_lisp_data and lisp_data_to_selection_data,
then see how bytes are decoded/encoded.

At least, with this Mozilla:
	Mozilla 1.0
	Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0)
	Gecko/20020615 Debian/1.0.0-3
I found very strange behavour.  It seems that Mozilla is
very sensitive to locale.

If you run Mozilla under LANG=ja_JP.eucjp, you can
copy&paste Japanese text with Emacs correctly.  But, in that
case, if you copy&paste latin-1 from Mozilla to Emacs,
Mozilla encode latin-1 by euc-jp while treating all latin-1
chars as JISX0212.  Thus, in that case, before pasting the
characters into Emacs, you must do C-x C-m X euc-jp RET.

And if you run Mozilla under LANG=de_DE, Mozilla correctly
handles latin-1, but doesn't handle Japanese characters at
all in copy&paste even if they are displayed correctly.

If you run Mozilla under LANG=C, Mozilla doesn't handle
latin-1 nor japanese characters in copy&paste.

non-ASCII cut/paste emacs <-> mozilla

[Miles Bader]

Has anyone else out there managed to get cut and paste between emacs and
mozilla (v1.0) working for non-ASCII text?  When I cut text out of
mozilla and paste it into emacs, I get a question-mark for each
noN-ASCII character; in the reverse direction, I get line-noise type
stuff that I assume is the raw encoding.

[selection-coding-system's value is `compound-text-with-extensions']

I think this is a mostly a problem with mozilla rather than with emacs
because emacs works slightly better with kterm (at least, I can cut text
out of kterm and paste it into emacs successfully), but mozilla
bug-reporting is much more daunting, so I'd like to see if anyone here
has any ideas first...

Thanks,

What is the character set of the non-ASCII characters you paste?  Also, 
can you please post one example of that ``line noise'' exactly as 
displayed by Mozilla?  Finally, does anything change if you use 
compound-text as your selection-coding-system?

It seems to happen with everything I've tried; I originally wanted to
cut/paste japanese characters, for which C-x = says:

    charset: japanese-jisx0208 (JISX0208.1983/1990 Japanese Kanji: ISO-IR-87.)

However, the same thing happens with `latin-iso8859-1' characters.

If I try to paste this word:     caf^[.A^[Ni
from emacs into mozilla, I get:  caf?

If I try to paste this word:     ^[$B3NG'^[(B 
from emacs into mozilla, I get:  <box>$(B3NG'<box>(B
where <box> is a little graphical box.

Interestingly enough, if I cut the above `<box>$(B3NG'<box>(B'
gibberish out of mozilla, and paste _that_ into emacs, it looks correct
in emacs!  So mozilla is apparently just pasting the raw encoded
characters from X, without interpretation.

[However, that _doesn't_ happen with the latin-1 characters -- the `?'
displayed in mozilla for `^[.A^[Ni' is apparently a real question-mark.]

No.

Yes, it looks like a ctext-encoded string.  You can verify that by 
setting a breakpoint in x_encode_text and looking at the string it is 
about to send to X.

Weird.  What system is that?

Debian unstable.

It seems as if it's just mozilla's problem, but I'm rather astonished
that it can't even deal with latin-1 characters.

Has anyone out there successfully used Mozilla to cut/paste non-ASCII text?

Also, does anyone know of any low-level tools that cat be used to
directly send/receive binary data to/from the X cut buffer mechanism, so
I can reduce the variables to one program?

Thanks,

Me too.  Does setting selection-coding-system to latin-1 change anything 
for Latin-1 characters?

Not really the answer you wanted, but using raw-text as 
selection-coding-system is one possibility to do something like that.
