On to your main topic: diacritics are only really useful for people who speak a language. To everyone else, such as the vast majority of the NYT's audience, they are purely a distraction. My own language uses some diacritics, and we basically never use them in international contexts. For example, if I have to write my address on a paper form outside my country, I won't ever write București, I will write Bucuresti, because it makes no difference to the reader and it may even confuse them. For example, if someone wrote their address on paper as "Đinh Lễ", I wouldn't be surprised if it got copied over as "Inh Le" street, with the person doing the copying assuming that the striketrhough was a correction, not a diacrtic.
