But the man page ALREADY says this:

       ***  WARNING  ***  The locale specified by the environment
affects sort
       order.  Set LC_ALL=C to get the traditional sort order that uses
native
       byte values.

What more are you proposing?

Unfortunately, no, this is not possible.  You're welcome to try and
write a patch to prove me wrong, but people have already had years of
experience of using environment variables as the way to tell a program
what encoding an input file uses, precisely because there is no other
obvious way of determining a file's locale.
