@Edent I read a fair amount of stuff with Vietnamese characters in — in particular character names in @aliettedb’s work. It blows my mind how often people don't account for Viet-only Latin-script characters. This (https://dataare.cool/@owenblacker/112247743990634454) is a recent example, where the Viet-only characters i-tilde, a-dot-below and y-dot-below were in roman-type because they didn't load Bookerly Italic for Latin Extended Additional. In a book that only uses 2 fonts and makes copious use of Vietnamese names.
