>Release: FreeBSD 2.2.8-RELEASE i386 and others
>Organization:
SibPTUS
>Environment:
FreeBSD box where russian (for example) locale is set.
>Description:
If you wanted to search simple russian phrase with grep(1),
then grep(1) returned unpredictable output.
>How-To-Repeat:
$ export LANG=ru_RU.KOI8-R
$ echo '27 ΣΕΞ' | grep '27 ΣΕΞ' # search '27 Sep' by russian
and grep's output is nothing
If input file contain many strings '27 ΣΕΞ', then grep returned
unpredictable output or nothing.
>Fix:
Workaround:
Using grep's -i option (if case sensitive not needed):
$ export LANG=ru_RU.KOI8-R
$ echo '27 ΣΕΞ' | grep -i '27 ΣΕΞ'
27 ΣΕΞ
