Weird, I get this summary:

I love how it looks, but the ">" thread indicator is shifting the
third line to the right by 1 space (the "63:" and everything after it
should be 1 space to the left).

Any suggestions?

Thanks
Ted

Often people change too many of the *-coding-system-* stuff without
being aware of the consequences and run into problems later.  Usually
it's enough to set the systems locale or use
`set-language-environment' in Emacs.

This depends only on the coding used for reading the .gnus.el file
(using a cookie as suggested, or putting the Unicode arrows stuff in a
separate file including a cookie).  

The locale and coding settings in Emacs are independent of this.  You
can use Unicode arrows in the summary with any locale and coding
system settings (e.g. I use a Latin-1 locale).

In the Summary buffer, `1 g koi TAB TAB' will give you a list of
available charsets.  I guess you want "koi8-r".  In
`mm-coding-system-priorities' you can use MIME charsets (in Gnus 5.10,
not in earlier Oort versions and 5.8/5.9) or Emacs coding systems.

I still have problems setting up unicode chars for emacs/debian.

locale says:

fab@rechner1:~$ locale

 (setq gnus-sum-thread-tree-root "┌▶")
 (setq gnus-sum-thread-tree-false-root "  ")

But I don't see them in my summary buffer. When I copy the summary-buffer it
looks nice; only the spaces between the vertical lines should be different:

I don't know the details of the abovementioned settings, so I would
just rely on Emacs to do the right thing.  :-)

Something like »alias emacs='LC_CTYPE=de_DE.utf8 emacs'« might do
this.

Ah, I see.  In the summary, the symbols are displayed as rectangles
(squares) when the line is bold or italics or some other face
different from the face in the other buffer.  Correct?  This means
that your default font for mule-unicode-* in Emacs is missing the bold
and/or italic glyphs.  (Same problem Ted mentioned in
<news:4n65ecqmtb.fsf@collins.bwh.harvard.edu>.)

Then you'll have two possibilities:

1) Install a font has has the glyphs, e.g. the efont-unicode package
   on SuSE.  On MGO the packages for Debian and Gentoo are mentioned,
   IIRC.

   See the thread around [1] (in the German Gnus newsgroup) for
   all the details.

2) Using %1{%B%} and `gnus-summary-line-format' to specify a non-bold
   display of the tree indicators in the summary, see the function
   `rs-gnus-summary-line-initialize' in my `rs-gnus-summary.el'.

  (copy-face 'default 'rs-gnus-face-1)
  (setq gnus-face-1 'rs-gnus-face-1)
  ;; Set line format:
  (setq gnus-summary-line-format
	"... %1{%B%} ...\n")

  I'm not sure if this is the recommended way to do this.  I don't
  really understand Emacs' font business.

Hm.  Put the cursor on the rectangle, press `C-u C-x =' and post the
output.  (I'm not sure if I can help you, as I'm not to familiar with
faces in Emacs, but maybe someone else has an idea.)  And show us the
value of `gnus-summary-line-format' (use `C-h v
gnus-summary-line-format RET').

The first (a news URL) allows to show this article in Gnus by fetching
it from news servers or Google (see the manual for details):

,----[ (info "(gnus)Finding the Parent") ]
|    Here's an example setting that will first try the current method, and

| 
|      (setq gnus-refer-article-method
|            '(current
|              (nnweb "google" (nnweb-type google))))
`----

The second is a link to Google.  Because of the newline and padding
spaces (valid according to the RFC 1738?), most newsreaders won't grok
it, but Gnus does.

Both should be buttonized (clickable) in Gnus by default.
