Re: [Patch] to correctly sort the items with emphasis marks in a list

["Juan Manuel Macías" <maciaschain@posteo.net>]

Hi Maxim,

Thanks again. In my case, I keep getting the wrong result. In addition
to the test I did in a virtual machine with Fedora, I use Arch Linux in
my every day computers, with locales correctly (I hope) configured as
es_ES.UTF-8 (there was a typo in my previous mail, sorry:
'en_ES.UTF-8'). In my /etc/locale.conf file I have:

LANG=es_ES.UTF-8
LC_ADDRESS=es_ES.UTF-8
LC_IDENTIFICATION=es_ES.UTF-8
LC_MEASUREMENT=es_ES.UTF-8
LC_MONETARY=es_ES.UTF-8
LC_NAME=es_ES.UTF-8
LC_NUMERIC=es_ES.UTF-8
LC_PAPER=es_ES.UTF-8
LC_TELEPHONE=es_ES.UTF-8
LC_TIME=es_ES.UTF-8

And with locale -a, I get a list of enabled locales:

C
en_US.utf8
es_ES.utf8
POSIX

However, I keep getting the wrong result :-( (Arch, Emacs 27.2).

Even with

LANG=en_EN.UTF-8 \
emacs -nw -Q -L ~/src/org-mode/lisp/ -L ~/src/org-mode/contrib/lisp/ \
list.org

Maybe the problem is on Arch's side (?), although it was also reproducible
in the test I did with Fedora in virtual machine and Emacs 27. 

Best regards,

Juan Manuel
