Eli> Can you describe here the current problems with VS-15?
CHAR+VS-15 and CHAR+VS-16 correctly choose text and emoji
representation, but CHAR+VS-15 results in the text representation only
if CHAR is not an emoji. If it is an emoji, the font selected for it
will always be the emoji font.
I=CA=BCve tried forcing font_range to use the font for the 'symbol' script
for EMOJI+VS-15, instead, but that resulted in composition
failing. Maybe there are some more dragons lurking in the composition
rules.

So the minimal change to get CHAR+VS-15 and CHAR+VS-16 to compose in
all our emoji test files is below. I noticed that we don=CA=BCt compose all
the sequences in emoji-test.txt correctly, but I=CA=BCll fix that on master

Yes, at least the semantics are clear (now that we know what they
are).

In the doc string of composition-function-table, I think. We already
document there the caveat of arranging rules in descending order of
look-back, which is part of the same "misfeature".

Not easily, because the display code calls subroutines of
find-composition in a certain order, and that's what causes the
behavior I described.
And even if we could make this happen, I'm not sure we should:
basically, having multiple matching slots would mean users and callers
will never be sure which one "wins".

OK, the issue is quite clear even without stepping with a debugger.
Bottom line: we cannot support a situation where the same character
can be composed by more than one slot in composition-function-table.
If there are more than a single slot for the same character, one of
them will be tried, and the rest will be ignored (not even tried).
In particular, if a character CH has a "forward" composition rule that
starts with itself, and also has a "backward" rule (one with non-zero
look-back parameter) triggered by a different character (which should
follow CH), the latter rule will never be tried.
This is what happens in this case: the character #x1F44D has several
rules that start with itself in emoji-zwj.el:
(#x1F44D .
,(eval-when-compile (regexp-opt
'(
"\N{U+1F44D}\N{U+1F3FB}"
"\N{U+1F44D}\N{U+1F3FC}"
"\N{U+1F44D}\N{U+1F3FD}"
"\N{U+1F44D}\N{U+1F3FE}"
"\N{U+1F44D}\N{U+1F3FF}"
))))
and it also has a "backward" rule:
(set-char-table-range
composition-function-table
#xFE0F '(["\\c.\ufe0f" 1 font-shape-gstring]))
The latter is triggered by #xFE0F and has a 1-character look-back,
which will match #x1F44D, since its category is '.' (it's a "base
character"). This latter rule is never tried. Why? because the
former rules, anchored at #X1F44D, are tried first (Emacs redisplay
examines characters in the order of their buffer positions), and fail
to match. When those rules fail to match, due to how the
composition-related functions called by the display engine are
factored, we never again consider compositions triggered by a later
character which "cover" also #x1F44D: once that position was examined
and the attempted composition failed, we move to the next character.
IOW, we assume that this first set of composition rules we find for a
given character are the only ones that could possibly be relevant for
that character.
Which means that to have #xFE0F compose correctly with Emoji
codepoints, we should include #xFE0F in the sequences in emoji-zwj.el.
The reason why "C-u C-x =" lies to us saying there's a composition
where really there isn't is because descr-text.el uses the
find-composition primitive, whose implementation is parallel and
separate from that of the display-engine routines, and is structured
differently. So find-composition does succeed to detect the second
rule, the one triggered by #xFE0F, which the display engine ignores.
I will think whether this can be fixed, to avoid such false positives,
but if we accept that there can be only one set of composition rules
for a character, then we basically invoked undefined behavior here,
and we got what we deserved.
Thanks.

OK, here's the scoop: there's no composition there. "C-u C-x =" says there is, but that's a lie: when I look in GDB at the glyphs actually shown there, there's no composition glyphs, only the glyph for U+1F44D followed by a glyph for U+FE0F. > but > > (set-char-table-range > composition-function-table > #x1F44D > '(["\U0001f44d\ufe0f" 0 font-shape-gstring])) > > gives me this, where the two '|' align perfectly. Here, there _is_ a composition. So there are two issues here: (a) why there's no composition in the first case, and (b) why does "C-u C-x =" says there is when there isn't.

composition rule for FE0F that looks backwards or one for 1F44D that
looks forwards. The sequence in both cases is
U+1F44D U+FE0F U+7C U+61
U+1F44D U+7C U+61
(set-char-table-range
composition-function-table
#xFE0F
'(["\\c.\ufe0f" 1 font-shape-gstring]))
produces the following:

There is a (very) thin space that shouldn=CA=BCt be there between the 1f44d
and the '|' on the line that has the FE0F (and since it follows the
value of glyphless-char-display-control, I don=CA=BCt think
it comes from the shaping engine).
but
(set-char-table-range
composition-function-table
#x1F44D=20
'(["\U0001f44d\ufe0f" 0 font-shape-gstring]))
gives me this, where the two '|' align perfectly.

Moreover, with Noto Color Emoji we get a single glyph. On my system, I have Noto Emoji, from which I get two glyphs: [0 1 128077 422 17 1 15 12 2 nil] [0 1 65039 3 17 0 1 0 1 [0 0 0]] (in which case I can understand why the second one is displayed as a hex box if I customize glyphless-char-display-control). So, given that this is the case, why is this wrong, again? If the font and the shaper produce two glyphs, or one glyph that looks like two, why should we think it's an Emacs's problem? (I verified that Emacs 28 shows the same, so this is not a recent regression.)

It still displays a single glyph with a thin-space. If I customize
`glyphless-char-display-control' to display hex codes for VS, then it
display a hex box.
So I guess that means we=CA=BCre not composing?

That's because the first one shows two glyphs that are
"pseudo-composed": not by the font, but by our hand-made "composition"
in compose-gstring-for-graphic. Try this instead:
(set-char-table-range
composition-function-table
#xFE0F
'(["\\c.\ufe0f" 1 font-shape-gstring]))
so that we only see a composition if the font indeed agrees to
compose. What do you see?

It=CA=BCs a single glyph, but that glyph contains a thin-space. I used this
to check, the second 'a' is slightly offset
=F0=9F=91=8D=EF=B8=8Fa
=F0=9F=91=8Da
This persists if I disable harfbuzz, and it behaves the same on macOS

Right. It looks the the FE0F entry is ignored. I=CA=BCve not ventured into

This is not what I see. I didn't use the above set-char-table-range
expression literally, but instead started "emacs -Q", and then
evaluated in *scratch*:
(set-char-table-range
composition-function-table
#xFE0F
'(["\\c.\ufe0f" 1 compose-gstring-for-graphic]))
After that, the sequence U+1F44D U+FE0F displays as a single glyph,
and there's no thin space after it. What am I missing? Is this
somehow specific to ftcrhb font driver or something?

You are saying that the entry in composition-function-table for
U+1F44D (and other similar characters) is used in preference to the
entry for U+FE0F that follows it, even though there's no U+1F3FB
etc. after it to "steal" the composition? Did you try stepping
through composite.c to see whether and why this is the case?

I think we need first to understand the issue at hand better. There's
more here than meets the eye, I think.

Eli> Yeah, I think it should go to master for now.
I pushed the doc changes, but not the code changes, because I now
think they=CA=BCre papering over a deeper bug (which we=CA=BCve noticed bef=
ore,
but didn=CA=BCt fix then).
In all these cases, consider the sequence U+1F44D U+FE0F
- emacs-29:
Displays as colour emoji, followed by an empty box
- emacs-29 with the following change in composite.el:
(set-char-table-range
composition-function-table
#xFE0F
`([,(purecopy "\\c.\ufe0f") 1 compose-gstring-for-graphic]))
Displays as colour emoji. Much rejoicing. If I follow my own
advice, and customize `glyphless-char-display-control' to show
hex-boxes for variation selectors, you then see that in actual
fact, we are still displaying the FE0F, but since it uses
thin-space by default, it wasn=CA=BCt obvious. Much sadness.
C-u C-x =3D:
display: composed to form "=F0=9F=91=8D=EF=B8=8F" (see be=
low)
Composed with the following character(s) "=EF=B8=8F" using this font:
ftcrhb:-GOOG-Noto Color Emoji-regular-normal-normal-*-13-*-*-*-m-0-is=
o10646-1
by these glyphs:
[0 1 128077 569 16 0 17 13 4 nil]
with these character(s):
=EF=B8=8F (#xfe0f) VARIATION SELECTOR-16
Now I notice (via emoji-variation-sequences.txt), that this is only
happening for the following codepoints.
U+1F408
U+1F415
U+1F426
U+1F446
U+1F447
U+1F448
U+1F449
U+1F44D
U+1F44E
And if I look in lisp/international/emoji-zwj.el, I find:
(#x1F44D .
,(eval-when-compile (regexp-opt
'(
"\N{U+1F44D}\N{U+1F3FB}"
"\N{U+1F44D}\N{U+1F3FC}"
"\N{U+1F44D}\N{U+1F3FD}"
"\N{U+1F44D}\N{U+1F3FE}"
"\N{U+1F44D}\N{U+1F3FF}"
))))
If I add
"\N{U+1F44D}\N{U+FE0F}"
to that, and undo the composite.el change, then everything is
fine. Hurrah! This means that the
`([,(purecopy "\\c.\\c^+") 1 compose-gstring-for-graphic]
[nil 0 compose-gstring-for-graphic])
is not doing the right thing for this case.
I can change the emoji-zwj.awk script to add CHAR+FE0F for all emoji,
unless someone knows how to fix composition to do the right thing
here.
(there are similar issues with CHAR+FE0E)

I=CA=BCm not sure: gedit displays the text representation, and libreoffice
displays the emoji presentation. And the google color emoji website
only shows colour glyphs. So I think it=CA=BCs up to the application to
select the correct font.

Selecting a non-Emoji font for a non-Emoji codepoints should > not need any special tricks. Actually, I don't understand why there's an issue here with font selection. Are you saying that using Noto Color Emoji with CHAR+0xFE0E, when CHAR is an Emoji character, doesn't produce the textual representation of CHAR? If so, isn't that a problem with the font? I thought all we needed to do was to hand the combination to an Emoji-aware font, and the font would do the rest. Now you seem to be saying that we somehow need to select a non-Emoji font? But if so, who'd guarantee that a font that cannot display Emoji will know what to do with the combination CHAR+0xFE0E?

It doesn=CA=BCt but in this case it *is* an emoji codepoint, so it displays
as emoji because of font.c, even when followed by VS-15.

Then you get the (composed) text presentation (and the composed emoji
presentation when it=CA=BCs CHAR+FE0F).

It requires something that answers the question "what font would we
use for this codepoint if it was not an emoji?". Maybe we can have a
separate fontset that pretends that the emoji script is equivalent to
symbol? Or invent some kind of 'text-presentation-font' property to
put somewhere?

It=CA=BCs a change to the VS-16 entry. We did discuss it before, and
decided to put it aside because the solutions all involved adding
composition-function-table entries for 0-9 or similar. I don=CA=BCt
remember why we didn=CA=BCt consider adding to VS-16=CA=BCs entry.
I=CA=BCll do some more testing, and post a final version hopefully this
weekend sometime.

OK. And what about CHAR+FE0E when CHAR is not an Emoji? Anyway, I think you should install the patch on emacs-29, and we should then try to fix the text-representation bug with VS-15 on master. (I guess it requires a change to font.c or something?) > Eli> Did you test the proposed change with the admin/emoji-*.txt files, to > Eli> make sure they all still display OK? > > Yes. Iʼve also got a change that makes Emoji_Keycap_Sequence work, but > I think we can leave that for master. Depends on the solution, I guess. Isn't it just a change to the VS-16's entry in composition-function-table? Or maybe a change in the #x20e3's entry? (Did we discus the Emoji_Keycap_Sequence case before?)

Welcome to the wonderful world of Unicode. The reason the table exists
is that there are codepoints that are *not* emoji, but they=CA=BCre part of
emoji sequences, so we still need to treat them as emoji in some
situations. Why Unicode didn=CA=BCt just make them emoji I don=CA=BCt know.

Not quite. If I don=CA=BCt have compose-gstring-for-graphic for VS-15, no
composition occurs for CHAR+FE0E. With my change you=CA=BCll get
composition, but it=CA=BCs still not 100% correct: CHAR+FE0E when CHAR is a

the extra empty box will not show, so it=CA=BCs still an improvement.

Yes. I=CA=BCve also got a change that makes Emoji_Keycap_Sequence work, but
I think we can leave that for master.

Both of these yield nil with this patch applied (and I haven't noticed any performance regressions). But it looks like you and Robert have a better patch so I'll leave you to it. However, I'd like to draw your attention to the existing hard-coded VS-16 table here: https://git.savannah.gnu.org/cgit/emacs.git/tree/admin/unidata/emoji-zwj.awk?h=4b3de748b0b04407d2492500c77905de56de1180#n72 It feels like this should either be the full table (the one in the patch) or it shouldn't exist at all. But again, I'm not the expert here.

Actually, I forgot about compose-gstring-for-variation-glyph. My
question was actually whether the general setting in
(let ((elt `([,(purecopy "\\c.\\c^+") 1 compose-gstring-for-graphic]
[nil 0 compose-gstring-for-graphic])))
(map-char-table
#'(lambda (key val)
(if (memq val '(Mn Mc Me))
(set-char-table-range composition-function-table key elt)))
unicode-category-table))
affects also the VS-n selectors. But since the latter setting of
(let ((elt '([".." 1 compose-gstring-for-variation-glyph])))
(set-char-table-range composition-function-table '(#xFE00 . #xFE0E) elt)
(set-char-table-range composition-function-table '(#xE0100 . #xE01EF) elt))
takes care of all the VS-n selectors except VS-16, and your patch now
will take care of VS-16, it sounds like we don't need to care about
other VS-n selectors?
Or are you saying that without including VS-15, CHAR+FE0E is not
displayed using its text representation?
Did you test the proposed change with the admin/emoji-*.txt files, to
make sure they all still display OK?

It has special support in compose-gstring-for-graphic, see there. The doc string also says a few words about that. We use this, e.g., in describe-char display, where we sometimes need to show a single combining character with no base character to combine it with. I think this is only relevant for accents and other such combining characters, not for VS-n. What does this issue mean for the other VS-n characters, though? Should we perhaps install something similar for them as well? Thanks.

Composition is done for 1f44d+fe0f, but I suspect that with the current
setup, composition is called again for FE0F, which results in the box
glyph. With the second patch we will only do backwards looking composition
for FE0F

You=CA=BCre right, there=CA=BCs no forward looking regexp, only a backwards=
one
and a no-regexp. But it=CA=BCs undeniable that:
[nil 0 compose-gstring-for-graphic]
causes the issue. I=CA=BCve never been clear on the semantics of that.

Ugh. The following fixes it for me:

AFAIU, this change will populate composition-function-table for many
"normal" characters, including ASCII digits and symbol/punctuation
characters from the 0x2xxx blocks. E.g., after you build Emacs with
this patch, what do the following evaluations yield:
M-: (aref composition-function-table ?0) RET
M-: (aref composition-function-table #x2122) RET
If they yield non-nil values, it could mean dramatic slowdown of
redisplay with these characters. Which is precisely what we wanted to
avoid when we made the decision which parts of the Unicode-defined
Emoji sequences to support in Emacs, and how to arrange for that
support to work.
The issue you site is strange: according to the "C-u C-x =" display
there, Emacs did compose #x1f44d with VS-16 using the Noto Color Emoji
font, so I don't quite understand why VS-16 is then also shown as an
empty rectangle. On my system Noto Color Emoji doesn't work, and "C-u
C-x =" says this instead:
Composed with the following character(s) "️" using this font:
harfbuzz:-outline-Noto Emoji-regular-normal-normal-mono-15-*-*-*-c-*-iso10646-1
by these glyphs:
[0 1 128077 422 19 2 17 14 2 nil]
[0 1 65039 3 19 0 1 0 1 [0 0 0]]
with these character(s):
️ (#xfe0f) VARIATION SELECTOR-16
which explains why I see two glyphs and not 1. But in the display
shown in the above issue, I see

This patch imports the full list from unicode.org instead of
special-casing a few characters as was done previously.
With this patch, '=F0=9F=91=8D=EF=B8=8F' (1F44D FE0F) should look the same =
as '=F0=9F=91=8D' (1F44D).
Without it, it will look like '=F0=9F=91=8D=E2=80=8C=EF=B8=8F'.
As a simple regression test, '=E2=9C=94' (2714) should still as "text" whil=
e '=E2=9C=94=EF=B8=8F'
(2714 FE0F) should still display as an emoji.
Fixes https://github.com/alphapapa/ement.el/issues/137
NOTE: I'm not a Unicode expert, nor do I understand how Emacs handles
Unicode (beyond what was required to implement this patch). But this
patch appears to work and I can't find any regressions.
