To contrast, I'm on macOS:

        $ echo $BASH_VERSION
        5.3.0(11)-maint
        $ locale
        LANG="en_US.UTF-8"

        LC_ALL=
        $ ls -1

        ¹.txt

        ₁.txt
        ₂.txt
        ₃.txt
        ₄.txt
        $ shopt -u globasciiranges
        $ ls -1 [0-5]*
        0.txt
        1.txt
        2.txt
        3.txt
        4.txt

I'm also on macOS.

Mac.lan(2)$ locale

2.txt
3.txt
4.txt
Mac.lan(2)$ shopt -s globasciiranges
Mac.lan(2)$ ls -1 [0-5]*
0.txt
1.txt
2.txt
3.txt
4.txt
Mac.lan(2)$ echo $BASH_VERSION
5.3.0(14)-maint

I assume this has to do with how APFS or HFS+ stores filenames (NFC vs.
NFD Unicode).
