Then please show me the place where you enter the
so far I do not know what you mean

After, choice artist, title, etc...
That is not what I referred to. I refer to the settings for the individual column - and that is described in the already linked section in documentation.
Please read the linked documentation in my first answer, including
Matching files from the text file to Mp3tag’s File List
Usually, Mp3tag uses the sequential order of the entries in the text file and applies it to the file at the same sequential position the the range of selected files. This means the files need to be in the same order as the entries in the text file.
You can use
%_filename_ext%or%_path%to perform matching based on the file name or the abolute file path respectively.
Okay, thanks. I hadn't seen that answer. 
Let's summarize:
Under Windows, the sorting of Mp3tag in terms of accents is what you want. I can confirm this here with my German Windows.
If you use Mp3tag in wine under Linux, it is not what you write.
For me, that can only mean that it is not Mp3tag's fault but rather your Wine/Linux work environment.
Alphabetical sorting is correct under Linux, whether in the file explorer, in file opening windows, in LO Calc, in the Xed text editor, etc.
In the terminal, the ls -l command sorts the files correctly.
I really don't understand...
That is definitely not a command in the Wine emulation. You have to separate native Linux programs from the ones running in the WIndows emulation.
No, it's a Linux command. But Puddletag doesn't work under Wine, but natively under Linux. So the problem lies elsewhere...
I must see in a Linux forum...
It works perfectly in Mp3tag, which eliminates the problem of alphabetical sorting (the preview in notepad is a valuable asset). Thanks.
Note: in Puddletag, it doesn't work. It doesn't recognize underscores.
Mp3tag: %_filename_ext% or %_path%
Puddletag : __filename or __path (2 underscores)
No problem...
