Incorporated in the attached final version of the patch.

It is complex. I am not sure if it is a bug or just some obscure
implementation detail. See Emacs bug#48740
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=48740

Subject: [PATCH] Make sure that fontification is preserved in agenda

* lisp/org-macs.el (org-string-width): Refactor old code and add
optional argument to return pixel width.  The old code used manual
parsing of text properties to find which parts of string are visible.
The new code defers this work to Emacs display engine via
`window-text-pixel-size'.  The visibility settings of current buffer
are taken into account.

(org--string-from-props): Removed.  It was only used by old
`org-string-width' code.

(org-buffer-substring-fontified): New function. Like
`buffer-substring', but make sure that the substring is fontified.

(org-looking-at-fontified): New function.  Like `looking-at', but make
sure that the match is fontified.

* lisp/org.el (org-get-heading): Make sure that heading is fontified.

(org--get-local-tags, org-get-tags, org-scan-tags): Add optional
argument `fontified'.  When non-nil, the returned tags are fontified.

* lisp/org-agenda.el (org-agenda-get-todos, org-agenda-get-progress,
org-agenda-get-deadlines, org-agenda-get-scheduled,
org-agenda-fix-displayed-tags, org-search-view, org-agenda-get-todos,
org-agenda-get-timestamps, org-agenda-get-sexps,
org-agenda-get-deadlines, org-agenda-get-progress,
org-agenda-get-blocks, org-tags-view, org-agenda-list, org-todo-list,
org-agenda-highlight-todo): Make sure that fontification is the same
with original Org buffers.  All the buffer-substring and match-data
queries are changed to ensure that region of interest is fontified.
Also, preserve composition properties, used i.e. by
`prettify-symbols-mode'.  The composition is usually set to be removed
on text change, so we do the changes inside
`with-silent-modifications'.

(org-agenda-align-tags): Use pixel width and (space . :align-to)
'display property to align tags in agenda.

(org-agenda-highlight-todo): Use `format' instead of `concat' to
update the headline in agenda.  `concat' may sometimes copy
composition property (see the C code) breaking the composed regions in
agenda view.  See Emacs bug#48740 for more details.

Preserve fontification and composition of headlines and tags in
agenda.  If the headlines/tags are not yet fontified when building
agenda, make sure that they are fontified in the original Org mode
buffers first.

In addition, tags alignment is now done pixel-wise to avoid alignment
issues with variable-pitch symbols that may appear in fontified Org
mode buffers.  The alignment is utilising :align-to specification,
which means that the alignment will be automatically updated as the
agenda buffer is resized.
