[Bug 2154042] [NEW] ls: files are not sorted in alphabetical order by default

[Harm van Bakel]

Public bug reported:

Since upgrading from Noble 24.04 to Resolute 26.04, files and folders
are not sorted in proper alphabetical order when running ls in Ptyxis.
The sort order appears roughly alphabetical but with many exceptions,
and there is no obvious pattern to explain the deviations. Casing does
not appear to be a factor either.

I tried switching locales but all of the following give incorrect sort
results:

LC_ALL=C /usr/bin/ls -hlF
LC_ALL=C /usr/bin/ls -hlF --group-directories-first

LC_ALL=en_US.UTF-8 /usr/bin/ls -hlF
LC_ALL=en_US.UTF-8 /usr/bin/ls -hlF --group-directories-first
