        How is that a disadvantage?  The user can easily force any
        locale of those available on the system with an explicit
        LC_ALL=, like:

$ LC_ALL=de_DE.UTF-8 sort < list.de 

$ LC_ALL=ru_RU.UTF-8 sort < list.ru 

$ LC_ALL=C sort < list.ascii 

        For one thing, M-x sort-lines seems to put ё after я, while in
        Russian it comes between е and ж.  And similarly for ß (and the
        accented letters) in German, etc.
