This was possible with LaTeX basically since forever, you need something
this in your preamble:
\usepackage[utf8]{inputenc}
\usepackage{lmodern}% or any other font
\usepackage[T1]{fontenc}
Since April 2018, you can drop the inputenc thing. The other challenge
was to find a font which covers the characters you need, and then assign
the correct encoding to it via fontenc. With the advent of XeTeX and
LuaTeX, you can drop the fontenc part as well.
Otherwise your patch LGTM.
Best, Arash

Hi Arash,
Thanks for your feedback concerning the accented characters --
I had no idea one could do this in "modern" (La)TeX. Please find

Thanks for pushing for clarity on this.
One thing I realized is that the implementation I had given of the new
function was incorrect in its handling of the frame argument, because
the function char-displayable-p does seem to depend upon the selected
frame (e.g., on a graphical terminal with multiple frames, each having
their own default face or font-backend).
Assuming I haven't misunderstood, I saw a few options for correcting the
new function:
1. Wrap char-displayable-p in (with-selected-frame ...).
2. Give char-displayable-p a frame argument, and wrap its body in
(with-selected-frame ...).
3. Drop the frame argument altogether (leaving (with-selected-frame
...) to callers of these functions).
Option (3) seemed simplest to me, and also at the least risk of
introducing confusion concerning the name of the new function: at a
glance, "char-displayable-on-frame-p" might suggest incorrectly that it
does the analogue for the given frame of what char-displayable-p does
for the selected frame. I went with (3) for now, but would be happy to
adjust if desired. Please see attached.

* lisp/international/mule.el (char-displayable-on-frame-p):
New function used to determine more reliably whether a character
can be meaningfully displayed.
* doc/lispref/display.texi (Fontsets): Document it.

prevents issues with missing characters appearing as boxes.

Hi Paul,
I suggest to drop this part. This notation kills kerning (due to
braces) and hyphenation when characters are constructed. The modern way
is to use a font which contains these chars (e.g., lmodern), set the
buffer encoding to UTF-8 and just enter the char. UTF-8 is standard for
LaTeX input since April 2018. I admit, this is LaTeX and not plain TeX,
but `tex--prettify-symbols-alist' deals mostly with LaTeX.
Best, Arash

"More reliable" will cause people wonder why we have "unreliable" APIs. But the essence is not the reliability, the essence is accuracy: char-displayable-p returns the ability of the entire Emacs session, whereas this new function returns the ability of a particular frame. I also think this function should be documented in the ELisp manual and in NEWS, but that could be a separate patch. Thanks.

Subject: [PATCH] Restrict symbol prettification to displayable ones
* lisp/international/mule.el (char-graphically-displayable-p):
New function used to determine more reliably whether a character
can be meaningfully displayed.
* lisp/progmodes/prog-mode.el
(prettify-symbols--composition-displayable-p): New function used
to restrict to displayable prettification symbols. This
prevents issues with missing characters appearing as boxes.
(prettify-symbols--make-keywords): Use it.

Thanks. With the attached patch, prettify-symbols-mode filters
prettify-symbols-alist to those entries that are displayable in the
following sense:
(let ((display-capability (char-displayable-p char)))
(if (display-graphic-p)
(or (eq display-capability t)
(fontp display-capability))
display-capability))
I've tested it in tex-mode, with GUI and terminal Emacs, using the
examples from this thread. Any feedback or other suggestions would be
welcome.

Subject: [PATCH] Restrict symbol prettification to displayable ones
* lisp/progmodes/prog-mode.el
(prettify-symbols--char-displayable-p)
(prettify-symbols--composition-displayable-p): New functions
used to restrict to displayable prettification symbols. This
prevents issues with missing characters appearing as boxes.
(prettify-symbols--make-keywords): Use them.

I tried, but wasn't able to extract the necessary information from char-displayable-p: In GUI Emacs, (char-displayable-p #x1F6F0) -> 'unicode and that character is not displayable for me (it renders as a white square). In Emacs -nw, (char-displayable-p #x1d550) -> 'unicode but that character displays normally for me. Thus, when the return value of char-displayable-p is 'unicode, I don't know how to determine whether the character would be displayable for our purposes (i.e., not as a white square). Any suggestions?

Ideally, we should only add those which can be displayed. The
function char-displayable-p should be able to tell. Would it be
possible to change the code such that only the symbols that pass that
test are added?
Thanks.

If I understand correctly, the concern is that if a font for a character
in the alist is unavailable, Emacs will display a white square. For
instance, on my machine (running macOS), adding
(add-to-list 'prettify-symbols-alist '("\\satellite" . #x1F6F0))
makes "\satellite" look like a white square when prettify-symbols-mode
is active.
So the question is whether the symbols introduced by this patch are more
likely to cause such issues than those already in
tex--prettify-symbols-alist.
Using (set-face-attribute 'default nil :font "...") and C-u C-x =, I
checked that DejaVu Sans supplies all the new symbols except those
attached to
\bigsqcup, \biguplus, "\ "
which are found in DejaVu Math TeX Gyre.
I checked that Arial has all the new symbols except those attached to
- \frac{1}{7}, \frac{1}{9}, \frac{1}{10}, \Game, found in DejaVu Sans
(like for \daleth).
- \Finv, found in American Typewriter (like for \cdot), and
- \bigodot, \bigoplus, \bigotimes, \bigsqcup, \biguplus, \iiiint, found
in DejaVu Math TeX Gyre.
Helvetica lacks many of the newly added and already present symbols.
This was a spot check, but it suggests that the new entries have similar
fallback behavior to existing ones, with the exception of a few
characters that depend on DejaVu Math TeX Gyre.
Perhaps the simplest way to avoid regressions would be to drop those
less well-supported symbols?
