> Vietnamese is one of the few recent adopters I know of to add unique accent marks, although they still use the same character set. This is an understatement of how complex the Vietnamese writing system is (I speak not a single word). https://en.wikipedia.org/wiki/Vietnamese_alphabet https://en.wikipedia.org/wiki/Vietnamese_alphabet They don't just have diacritics, they _stack_ them to form towers of diacritics. Ok, so only 2 high, but even so.
