I no longer apply for numbers.
If possible, make the correct sorting of cyrillic letters.
Thank you!

Libre Office, analog Microsoft Office, has a unique sorting algorithm?

I wrote my observation.
I do not understand the difference .Net & Win32 API
Sorry

I compared with the editor E-Channelizer
Sorting by letters is correct (small, big letter), by numbers is the same 1, 10, 11, 12, 2, 3, 4....

I'm unfortunately not a programmer.
But as I understand from the links, the code is working.

OK!
There are many ready-made examples and descriptions in Russian.
I do not know if it will help you, but just in case, I'll give you links.

It does not allow to make a ready Delphi library?
Or is it something you can do manually?

Ээ, Юю, Яя - last letters
See picture :)|))

But this is wrong.
After 1 the next digit is 2, not 11.

Sorting a large and uppercase letter is also incorrect.

there must be a sequence, at the end of the list a small letter is obtained, after all the big ones.

Hmmm...
In German and English, is it the same?
If so, then the language of Delphi is obsolete.
It is not right to arrange numbers - it's ALL!

The problem is not only in the Alphabet, the problem is also in numbers.
They are the same for all languages.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ...
Sorts
1, 10, 11, 12, 2 ...
