Not in the Czech alphabet: a, á, b, c, č, d, ď, e, é, ě, ...

Also, we regard 'Ch' as its own letter. So yeah, try sorting alphabetically. I'll wait.

Well in my language "é" is absolutely not special, and should definitively be placed near "e" (to the point that uppercase é is often written E instead of É)

It depends on the language. Unicode defines rules for it: https://www.unicode.org/reports/tr10/

If I recall correctly, the default propose a first list that push items which are guessed most likely what the user expect, then a list more complete, and in any case let you filter by typing. I think it also can change the way it behave if you are connected and tweaked your preferences in the matter for your account.

Wikipedia uses UCA sort order in categories (depending on which lang wikipedia you are reading). Most other lists just sort using unicode codepoint order (in NFC). So it depends, but yes, for generated lists other than categories ascii characters usually come first.

That’s English hegemony. Languages have their own sorting that they expect. You can’t impose rules to other languages.

Of course at some point Unicode needs to be ordered, but you don’t get to impose technical details to people around the world because it matches with how English does it.

That’s where geo-ip guessing becomes relevant. Show a list with the most likely languages at the top.

Sorting by character codes, yes.

But in the language native locale, no.
