It _could_ be much worse, there's no doubt about that. Different fonts use very different styles for the same glyphs.

I guess so. I'm surprised that DejaVu Sans Mono is broken, though, so
perhaps there is something else going on.
This reminds me of a related thing I've wondered about: We don't combine
glyphs from different fonts, because this may look very ugly. But has
anybody tried doing it anyway? It may not look worse than what some
people are seeing today...

It=CA=BCs possible, since we do something similar for certain emoji
sequences. I question whether it=CA=BCs worth doing, though, it seems like
very much a rare condition, which is easily fixed by switching fonts.

xfthb:-PfEd-DejaVu Sans Mono-normal-normal-normal-*-22-*-*-*-m-0-iso10646-1
by these glyphs:
[0 1 1071 878 13 0 13 16 0 nil]
[0 1 769 649 13 4 11 17 -13 [0 0 0]]
explicitly says that character composition _did_ happen here, it's
just the display that is broken. And I guess that moving point to
these characters will show a "fat" cursor that includes both the base
character and the accent, once again showing that Emacs did compose
the accent with the preceding character.
