Title:
  sort inconsistent

Status in “eglibc” package in Ubuntu:
  Won't Fix

Bug description:
  In the following examples, I expect /usr/bin/sort to always put '.'
  (0x2E) before 'a' (0x61)

  $ echo -e 'ab\naa\n.a' |sort
  .a
  aa
  ab

  $ echo -e 'aba\naaa\n.aa' |sort
  .aa
  aaa
  aba

  $ echo -e 'abb\naaa\n.ab' |sort
  aaa
  .ab
  abb

  The difference between examples 2 and 3 is the third byte of each line
  is one bit higher, and for some reason this makes the first byte "."
  simultaneously after "a" and before "a" in sort order.  That's should
  be contradictory, and this is repeatable.

  This also happens when other punctuation marks are the first byte (remember 'a' is 0x61)
  $ echo -e 'abb\naaa\n!ab' |sort  # ! = 0x21
  $ echo -e 'abb\naaa\n_ab' |sort # _ = 0x5F
  $ echo -e 'abb\naaa\n{ab' |sort # { = 0x7B , so not only for bytes that are  < 0x61
