Thanks for the report. However, this is not a bug in sort, but a
problem of your current choice of locale. It is also a FAQ:

Running with the recently introduced 'sort --debug' option sheds some
light on your situation:
$ printf 'a\nj\nA\ni\nAA\nB\n' | src/sort --debug
src/sort: using `en_US.UTF-8' sorting rules
a
_
A
_
AA
__
B
_
i
_
j
_
address@hidden (0 0) ~/coreutils
$ printf 'a\nj\nA\ni\nAA\nB\n' | LC_ALL=C src/sort --debug
src/sort: using simple byte comparison
A
_
AA
__
B
_
a
_
i

j
