I copied the source code of `sort-lines' and adapted the call to `sort-subr' to use `string-collate-lessp', resulting in this function: (defun my-sort-lines-collate (reverse beg end) (interactive "P\nr") (save-excursion (save-restriction (narrow-to-region beg end) (goto-char (point-min)) (let ;; To make `end-of-line' and etc. to ignore fields. ((inhibit-field-text-motion t)) (sort-subr reverse 'forward-line 'end-of-line nil nil 'string-collate-lessp))))) This function, when called, only results in an error "Wrong type argument: stringp" (tested in `emacs -Q'). Interestingly, if the 6th argument to `sort-subr' is changed to `string<' (which is said to be the default value!) the very same error results. It does not make a difference to explicitely define it with a lambda instead: (defun my-sort-lines-collate (reverse beg end) (interactive "P\nr") (save-excursion (save-restriction (narrow-to-region beg end) (goto-char (point-min)) (let ;; To make `end-of-line' and etc. to ignore fields. ((inhibit-field-text-motion t)) (sort-subr reverse 'forward-line 'end-of-line nil nil (lambda (a b) (string-collate-lessp a b))))))) This code results in the same error. I assume this is a kind of bug. Either way, I'd like to request as a feature a variant of `sort-lines' that is aware of the locale's sorting rules.
