Unless we have user complaints with real-world use-cases, I am leaning towards keeping things consistent with Emacs. Including Emacs-wide fallback for `string-collate-lessp'. This will make our life easier. Maintaining an Org-specific fallback will (1) cost maintenance time; (2) may confuse users used to global Emacs behaviour; (3) has no clear benefit other than our theoretical discussion. > The only additional consideration is that compare function should be > configurable.

We can introduce a new customization - `org-string-sort-function' that will be used across Org mode to sort user text. It would be even better to allow smart sort function that depends on document #+language, but I do not see an easy way to implement such feature - `string-collate-lessp' does accept LOCALE argument, but I have no idea how to link #+LANGUAGE to locale deterministically. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
