I have a similar issue (Libra 2 with 4.38.21908) with kepub books that contain some pali or sanskrit words with diacritics. Noto Serif Devanagari is forced as supplemental font (needs to be downloaded from Kobo) even though it doesn't have all of the glyphs needed. This happens even if the selected side-loaded reading font or the publisher font included in the book does have all the glyphs needed (and the words with diacritics are shown correctly without the need for a supplemental font)
Several issues with that:
1) An annoying pop-up "Noto Serif Devanagari has been turned on as a supplemental font for this book" pops up not just the first time the book is opened, but also sometimes (not always) when the book is opened again although the supplemental font has already been turned on before.
2) The Noto Serif Devanagari font doesn't make sense as supplemental font because it doesn't have the glyphs needed
3) Setting another supplemental font (side-loaded) instead that does have all the glyphs needed doesn't have any effect. (But this font does show all the glyphs correctly when selecting it as the reading font).
It seems that the supplemental font feature doesn't work at all and just creates problems with annoying pop-ups.
Has anyone come across a book where this supplemental font feature actually works? Is there any workaround to get rid of the anyoing pop-up or to disable the whole supplemental font feature (other than using epub instead of kepub)?
