Thanks for replies,

I am using:
GNU Emacs 26.1 (build 1, x86_64-apple-darwin14.5.0, NS appkit-1348.17
Version 10.10.5 (Build 14F2511)) of 2018-05-31


This is what I get:

    (string-collate-lessp "a" "x" "de_DE.utf-8" nil) ; t
    (string-collate-lessp "a" "X" "de_DE.utf-8" t) ; nil
    (string-collate-lessp "a" "x" "fi_FI.utf-8" nil) ; t
    (string-collate-lessp "a" "X" "fi_FI.utf-8" t) ; nil


I think I have lost the sense how Emacs language environments work
after struggling for years with buffers getting automatically
converted to Latin-1. I started setting all possible variables to
'UTF-8 and finally something did it.

Now I tried again various values to see if they affect the org table
sorting:

(set-language-environment 'utf-8)
(set-language-environment 'English)
(set-language-environment 'Swedish)

(setq locale-coding-system 'utf-8)
(setq locale-coding-system 'fi_FI.utf-8)
(setq locale-coding-system 'de_DE.utf-8)
(setq locale-coding-system 'en_GB.utf-8)

Unfortunately none of these made any difference. Any suggestions?

I am testing sorting in a simple one column table:

| a |
| c |
| B |
| D |
