The new homoglyph face introduced in
c06a518b5b0706509252abb03875867b10a92fc7 is being used for displaying
characters in Gnu and eww buffers. Those characters look like sore
thumbs, very displeasing.
I have no idea why the curly things are being replaced. I'm using a
graphics terminal (X on GNU/Linux). This is describe-char from a eww
buffer:
position: 426 of 6337 (7%), column: 143
character: ‘ (displayed as ‘) (codepoint 8216, #o20030, #x2018)
preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0x2018
script: symbol
syntax: . which means: punctuation
category: .:Base, <:Not at eol, c:Chinese, h:Korean, j:Japanese
to input: type "C-x 8 RET 2018" or "C-x 8 RET LEFT SINGLE QUOTATION MARK"
buffer code: #xE2 #x80 #x98
file code: #xE2 #x80 #x98 (encoded by coding system raw-text-unix)
display: by display table entry [?`] (see below)
The display table entry is displayed by these fonts (glyph codes):
`: xft:-PfEd-DejaVu Sans-normal-normal-normal-*-19-*-*-*-*-0-iso10646-1 (#x43)
face: ‘homoglyph’
Character code properties: customize what to show
name: LEFT SINGLE QUOTATION MARK
old-name: SINGLE TURNED COMMA QUOTATION MARK
general-category: Pi (Punctuation, Initial quote)
decomposition: (8216) ('‘')
There are text properties here:
face variable-pitch
Another one, with a different font, from a Gnus Summary buffer:
position: 1484 of 13282 (11%), column: 35
character: “ (displayed as “) (codepoint 8220, #o20034, #x201c)
preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0x201C
script: symbol

file code: #xE2 #x80 #x9C (encoded by coding system nil)

Could you please mention a couple of Web pages where you see this?
Also, do you see something different in 25.1.50?
Thanks.

It happens with this, for instance:

I can seek a good revision if that's important. But while trying to
reproduce the bug, I noticed that emacs -Q is not affected, nor a
regular emacs session (that loads my config) but the session I'm running
as a daemon does show the problem. I think that that is the real
trigger. Can you try visiting the web page above with a daemonized emacs
on GNU/Linux? Or can you tell me what data to inspect to know if Emacs
decided to show those chars on a translated form when the daemon
started?

Indeed, the problem is that standard-display-table is set by
startup--setup-quote-display when the daemon starts and it is used for
all terminals.
This model seems wrong. An Emacs server can have several terminals. We
need a substitution table (an standard-display-table) for each terminal,
don't we?
BTW, as a quick workaround, setting standard-display-table to nil solves
the problem.

Each window can have its own display table. I suggested to use this
back when Paul implemented this feature.

Yes, that sounds like the right fix, though it'll take some work.
Alternatively, Óscar, perhaps you could give me hints about how to change
startup--setup-quote-display so that it guesses the right way for your setup. I
expect this will be simpler.

There is nothing special about my setup. `emacs --daemon' is executed
when my destkop environment (KDE) starts, and that's it.
I guess the problem is reproducible simply with:
$ emacs --daemon -Q
$ emacsclient -c -n
M-x eww http://debbugs.gnu.org/cgi/bugreport.cgi?bug=24772
I could hack startup--setup-quote-display to detect that there is a
graphical environment present, but then the substitution would fail when
a frame is created from a text terminal (while remotely accessing the
server from ssh or from a Linux virtual terminal on the same machine.)
We all agree that the correct way is to use an specific display table
for the characteristics of each terminal. Until the proper fix is
implemented, it is up to you to decide if the feature deserves to be
disabled (I can put the workaround on my config file, so no hurry here.)

Most probably because when the daemon starts, it has no window system,
so the test for these characters being displayable fails.

Is this still a problem for you? The page displays well for me on the
Emacs trunk with eww.
