It might be related to collation. Are ü and u sorted together? ß? Æ? Is Å its own letter?
Is it John Smith or Smith, John? Is there a Canonical Ordering?
Chinese seems to go by $FamilyName $GivenName as the "canonical order". French people do use the regular order but in some occasions do write it as FAMILYNAME GivenName
The EU also likes to do this, perhaps so HUNGARIAN Dude isn't called "Mr. Dude".
Which is what I think the original list is claiming.
Not only ordering but equality. So for example Müller and Mueller might be considered equal in German.
Edit: Just found an interesting example, Linkedin orders Á after Z (where the correct in most places would be to sort it together with A), after that, letters in different alphabets (correct) then the emoticons (well, people do add that to their names...)
Ordering also depends on the context. Usually "ä" is sorted like "a", but in lists of names it's sorted like "ae".
5: Middle names are common but optional in the UK, I have one but my dad had two.
6: my full name, including middle name, is longer than the default space available in most paper forms which gives you separate box for each letter. String together any three 8-character first/middle/family names for same effect
7/8: In 2002, Richard James changed his name to “Mr Yellow-Rat Foxysquirrel Fairydiddle”, in exchange for a pint of beer.
9: Ἑλένη, نهاد وديع حداد, 蔡英文, ⴰⴳⵍⵍⵉⴷ ⵎⵓⵃⴰⵎⵎⴷ ⵙⴷⵉⵙ, …
10: Would الملك محمد السادس / ⴰⴳⵍⵍⵉⴷ ⵎⵓⵃⴰⵎⵎⴷ ⵙⴷⵉⵙ count? Or is this about mixing rather than having multiple variants for different character sets?
11/12/13: I don’t know how to even find examples
14: “-son” is a suffix?
15: “Number 16 Bus Shelter”, New Zealand: https://www.nzherald.co.nz/nz/number-16-bus-shelter-violence...
16/17: same problem searching as 12/13
18: I need help with this one too

21/22/23: Back in my first job, one guy called Mark Thompson had to collaborate with another guy in the same company also called Mark Thompson. Neither of these two was the Director General of the BBC, the author, the DJ, the newscaster, the reporter, the chemist, nor either the Arizona or Minnesota politicians.
24: China’s, what, 20% of world population now? Lots of rich Chinese people around, you probably do want to be able to support them.
25/26/27: likewise
28: probably has happened, given what people are like
29: Migration also happens (I am one)
30: I assume this is about going between character sets? In which case: is “Colin” transliterated as in the American (Colin Powell) or the British (Colin Firth)? Lossless has the same issue in the other direction, but it’s harder to give examples
31: Bad words for programming safety:

Rude surnames in English include: https://en.m.wikipedia.org/wiki/Dicks_(surname)
32-36: I don’t know anything about this, beyond that it can happen surprisingly late
37: Chinese citizens living in America, with a Chinese state database entry with their actual name plus something in America that doesn’t support non-ASCII which has a crude attempt at a transliteration.
38: Depends what you mean by “well designed”. Starbucks’ coffee-writing is pretty infamous for the amusing errors, and that’s without even getting as far as bits.
Then you have the extra problem of the difference between the ü character (U+00FC) and u+(combining diaeresis (U+0308)).
39: wherever you’re from, most people are from elsewhere.
40: same problem as 11/12/13
