bug#15420: 24.3; Symbols like 🚴 (U+1F6B4) are not displayed by default

[Mike FABIAN]

After emacs -Q, try to load a file containing

🚲 U+1F6B2 BICYCLE
🚴 U+1F6B4 BICYCLIST
𓀀 U+13000 EGYPTIAN HIEROGLYPH A001

Glyhps for these characters are not displayed by default,
even when fonts with these glyphs are installed.

For example "Symbola" by George Douros (http://users.teilar.gr/~g1951d/)
has 🚲 U+1F6B2 BICYCLE and 🚴 U+1F6B4 BICYCLIST and
"Noto Sans Egyptian Hieroglyphs" from Google has 𓀀 U+13000 EGYPTIAN
HIEROGLYPH A001.

Instead boxes showing the codepoints are displayed.

A patch like the following to fontset.el can make this
work by default:

But I am not sure whether this patch is the right way to do it.
Because it seems strange having to hardcode the font
names "Symbola" and "Noto Sans Egyptian Hieroglyphs".

Is there any other way to do it?

Isn’t it possible to make glyphs for such symbols display correctly by
default if *any* font containing these symbols is installed on
the system? How?

(I'm going through old bug reports that have unfortunately gotten no
responses yet.)

I tried reproducing this in Emacs 27 (under Linux).  I installed the
Symbola fonts and started an Emacs, and it displayed the bicycle
characters without any problems, so I'm unable to reproduce this bug.

Are you still seeing it, or has it been fixed during the intervening
years?

I have both the Symbola and Aegyptus fonts installed; when I run emacs
with -Q, only the bicycle and bicyclist characters are correctly
displayed, the Egyptian hieroglyph is displayed as a hex box.  But when
I then set the default font (e.g. via the Options menu) to Aegyptus
Regular, all three characters are correctly displayed.  So the installed
Symbola fonts are found by default, but not the installed Aegyptus
fonts.

For years I did build with my little extra  patch on top of git master,
like this:

commit 258c86a974f788a33a019a082473781a2a603043
Author: Mike FABIAN <mfabian@redhat.com>
Date:   Tue Sep 17 18:41:50 2013 +0200

    Display some symbols correctly by default
    
    For example display U+1F6B4 BICYCLIST and Egyptian Hieroglyphs
    correctly by default.

diff --git a/lisp/international/fontset.el b/lisp/international/fontset.el

But now I tried again with current master without that patch and it
worked. Symbola was used for the bicycles and "Noto Sans  Egyption
Hieroglyphs" for the  hieroglyph even without my patch. So something
seems to have been fixed.

You will see in lisp/international/fontset.el that the #x1F680 --
#x1F6FF block is now configured to use Symbola by default, which is
why the BICYCLE and BICYCLIST are displayed without any changes.  As
for the Egyptian Hieroglyphs, we don't do anything about them, so if
you see a change in behavior, that must be due to some changes on your
system not directly related to Emacs.  In general, the hieroglyphs
still require fontset customizations, because most fonts that support
them don't explicitly announce that support (and the number of fonts
supporting Egyptian Hieroglyphs is very small anyway, and most of them
aren't free).

In any case, this is not a bug, and I see nothing we can do here to
make the situation significantly better.  Users who want the
hieroglyphs will have to customize their fontset.

Is this for technical reasons (e.g. redisplay speed) or a policy
decision such as not enough free fonts?  I ask because e.g. Firefox
seems to automatically find an installed font; for example, on my system
Firefox displays the hieroglyphs on
<https://en.wikipedia.org/wiki/Egyptian_Hieroglyphs_(Unicode_block)>,
presumably using the Aegyptus fonts installed in my system, while EWW
does not display the hieroglyphs (but does e.g. display the emoticons on
<https://en.wikipedia.org/wiki/Emoticons_(Unicode_block)>, some using
DejaVu, some using Symbola).

It probably means that Aegyptus doesn't announce any features we are
looking for when searching for a suitable font.  Or maybe the Egyptian
Hieroglyphs lack something in our data structures used for font
lookup (see fontset.el).

Firefox has a long list of known fonts stored in its database out of
the box.  We don't for 2 reasons: (1) we don't want to reference
non-free fonts, and (2) we want to be able to support the use case of
installing a font while the session runs.

The above may or may not be relevant to the Egyptian Hieroglyphs case;
volunteers are welcome to step through the font lookup process in
Emacs in that case and see whether we should add something to our
fontset-related databases.  After all, this script is quite rare, and
was added to Unicode at a relatively late date, so something might be
amiss.

I see you added support for displaying Egyptian hieroglyphs by default

Does that change the result on your system in any way?  Because I'm
not sure what I did is enough to make any difference.

Yes it does: when I start with -Q and visit
<https://en.wikipedia.org/wiki/Egyptian_Hieroglyphs_(Unicode_block)> in
EWW, I now see all the hieroglyphs, just like in Firefox.

And I tried just now (after installing fonts-symbola and
fonts-noto-core, and this displays correctly for me from -Q:
