I would want to see some data on tokenization for some real-world examples. "Je voudrais une pizza" actually translates more directly to "I would like a pizza" which is 5 tokens. But also I think there's some danger here in terms of this might be cherrypicking examples. Spanish is a lot more dense than English or French and might tokenize better. (I see "quiero pizza" is 4 tokens which seems like the right number of tokens to me - "quiero" actually contains "I want <present tense>") You could argue it's 2 or 3 tokens but 4 seems preferable.

For diacratics in French or Spanish, diacratics are logically characters. I can't think of an example where it's actually useful to split the letter into a different token but I could see it happening and not being harmful. I do think it's possible French is just weird and just needs more tokens. When I think about how I process French, I probably do treat e.g. "Je l'ai aimé" as a pathological example as 3 tokens when I speak it out loud. But I can also see why you would tokenize it as 6 tokens, I'm not sure that's Anglocentrism so much as it's recognizing a complexity difference between French and English writing.

But all this is contrast to how non-roman characters are tokenized at the byte level. That just seems bad and like it's definitely going to make it worse with non-roman languages. There's no point in having tokens that split characters.
