What is ObsidianMD's "Natural Order Sorting"? (Full list or point to specs)

So I’ve checked out the forums, docs, Wikipedia, etc for this (and perhaps I missed it in my fervor), and I couldn’t find which “Natural Order Sorting” it uses.

-forum.obsidian.md /t/file-tree-inconsistent-sort-order-with-alphas-numerals-for-files-and-folders/111559

ObsidianMD sorts the “valid” characters as following:

_
-
,
!
. //not normally allowed
@
&
%
`
+
=
~
$
1
01
2
10
A
z


Windows and other stuff go a bit like this



!

$

%

&

,

.

'

-

@

_

`

~

+

=

Does ObsidianMD match a UNIX locale I can find?

Yes I am aware there’s a Custom Sort plugin found here: -github.com SebastianMC/obsidian-custom-sort
