Description Petr Pisar 2013-11-13 08:30:39 UTC 
$ printf 'A\nB\na\n' | LC_ALL=en_US.UTF-8 sort -i
A
B
a
$ rpm -qf $(type -p sort)
coreutils-8.21-20.fc21.x86_64

This probably because of broken multi-byte patch (bug #1003544) because coreutils-8.21-16.fc20.x86_64 sorts as expected:

$ printf 'A\nB\na\n' | LC_ALL=en_US.UTF-8 sort -i
a
A
B
Comment 1 Ondrej Vasik 2013-11-13 13:23:44 UTC 
Does occur even with the C locales... btw. -i doesn't mean case insensitive sort - it does mean "ignore nonprinting characters". I think you want -f option, which seems to work properly.

With coreutils-8.21-20 (compiled on RHEL-6)
printf 'A\nB\na\nb\n' | LC_ALL=C ./sort -i
A
B
a
b

printf 'A\nB\na\n' | LC_ALL=C ./sort -f
A
a
B

printf 'A\nB\na\n' | LC_ALL=en_US.UTF-8 ./sort -f
A
a
B

For me, it looks more like something was fixed than broken. Can you confirm?

God damn! I lived in a lie until now. The `-f' option works for me. I tested it  in en_US.UTF-8, cs_CZ.UTF-8 and C locales.
