Each item have to be split into logical units and locale-aware multilevel comparison should be applied to each unit separately. E.g. for description list, only term should be compared at first to properly order emphasized items, it does not matter if description starts from "a" or from "z". Simple `string-collate-lessp' for whole item uses further levels only strings are considered identical on previous levels. I had an idea to augment sort keys with some text properties for custom string comparator, but I decided that such complications would not ensure reliable sort for all possible cases. - A :: B - /A/ :: C - *A* :: A However `org-sort-remove invisible' still has some room for improvements (it is not mandatory in my opinion).
