GOod question. I guess so. I don't know how the pdfs are produced,
but from looking at the problematic examples it seems that for
combining say "a" with some diacritic foo it does the following:
	print "a"
	go back the width of "a"
	print foo
but what it should do is
	print "a"
	go back width of "a"
	print foo
	go forward width of "a" - width of foo
But to be honest, that is WILD WILD guessing.

Yes, known. I have opened a bug some time ago against fontconfig. THee
is a reason for that. At some point, and I don't know if it is
still like this, some of the fonts in the texmf trees were not 
well behaved, declaring wrong encodings etc. THis is ok as long as you
use them only in TeX world because there the encodings are done for
each font, but if you access them with font config then you might
see garble.

So the trigger should actually be removed.

OTOH, someone (definetly not me!) could go through the fonts (all, or only
ttf/otf) shipped in texlive-* and realted packages, or all fonts under
/usr/share/texmf/fonts and /usr/share/texlive/texmf-dist/fonts/ and
check the fonts whether they are ok (don't ask me to define what means
ok!) and link those fonts into /usr/share/fonts which is crawled by
fontconfig.

Best wishes

TREWOFFE (n.)
A very thick and heavy drift of snow balanced precariously on the
edge of a door porch waiting for what it judges to be the correct
moment to fall. From the ancient Greek legend 'The Treewofe of
Damocles'.
