[Message part 1 (text/plain, inline)]

The standard boxquote looks like this:

,----[ title ]
| Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi et
| dolor vitae quam fringilla vulputate ac id sapien. Nullam auctor
| consequat magna in fringilla. Praesent sed dolor vel felis
| condimentum faucibus eget in risus. Phasellus dignissim vehicula
| purus, non tempus arcu rutrum vel.
`----

However, since Emacs now has perfectly good Unicode support, the
following shows boxquote configured to use standard Unicode line drawing
characters with rounded corners:

(set-variable 'boxquote-bottom-corner "╰")   ; U+2570
(set-variable 'boxquote-side "│ ")           ; U+2572 + space
(set-variable 'boxquote-top-and-tail "────") ; U+2500 (×4)
(set-variable 'boxquote-top-corner "╭")      ; U+256F

╭────[ title ]
│ Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi et
│ dolor vitae quam fringilla vulputate ac id sapien. Nullam auctor
│ consequat magna in fringilla. Praesent sed dolor vel felis
│ condimentum faucibus eget in risus. Phasellus dignissim vehicula
│ purus, non tempus arcu rutrum vel.
╰────

Much nicer!  It would be great if these could be made the default in
place of the ugly ASCII.

Boxquote is not part of the standard Emacs. I guess you need to contact
the author of boxquote.el or someone who distributes your version of
Emacs.

Ah, sorry, I didn't realise it was part of an extension package
(emacs-goodies-el).

Sure doesn't look nicer to me! See attachment.

Boxquote should not use Unicode characters unless the buffer is already Unicode
encoded. Even then, I'm not convinced the Unicode version looks better.

I think your font is to blame here; perhaps it's using a fallback as
the corners, and as a result they don't line up correctly.  Even so,
IMO this looks (subjectively) better than ASCII.  I agree that
using Unicode characters in a non-Unicode buffer would be wrong;
boxquote should use a fallback in that case (can Emacs do
transliteration for non-representable characters when you insert
characters not represented in the buffer encoding)?

Anyhow, I'll pass this along to the author, since it's not part of
Emacs itself.

Roger

That's with emacs -Q on MS Windows - IOW, the default font.
