bug#23831: 25.0.95; face Info-quoted is not displayed on Redhat 6.6

H. Dieter Wilhelm

I'm calling from "emacs -Q" the info system with `C-h i' and any
character in Info between quotes are just displayed with a rectangular
box.  I'm compiling Emacs on an elderly RHEL at work.  What can I do to
enable Emacs to display the info files in a readable way?

Thank you very much

      Dieter

I think you want to customize the variable 'text-quoting-style'.

That doesn't make any difference to this issue. This does:

(eval-after-load "info" '(copy-face 'default 'Info-quoted))


One final try to repeat my comments from bug#19889 and 22207:


Viewing Info files is an important part of Emacs. I think it is a
mistake to break the rendering of them in this way, even if it's only on
a small fraction of systems, for the sake of a very minor (and IMO
arguable; cf http://debbugs.gnu.org/19889#115: "an ugly font") cosmetic
improvement on the rest.

Please make Info-quoted face inherit from either default or
font-lock-string (on emacs-25, the situation is somewhat better on
master).

That is true.

What I found strange is though that it also didn't change the actual
quoting characters in my *info* buffer, do I have to restart Emacs for
t-q-s to take effect?

That is also true. :-)

Thanks a lot!

It seems like the OP has found the fix for his problem, but is there
anything more to do here?

No, I don't think so.  We nowadays probe the display for the ability
to show these characters, and use ASCII replacements if not, so I
think the situation now is better than then.
