Or is this expected? $ seq 2 | env LC_ALL=C grep --null-data --quiet '[12].2' ; echo $? 0 $ seq 2 | env LC_ALL=C grep --null-data --quiet '[1-2].2' ; echo $? 0 $ seq 2 | env LC_ALL=en_US.iso88591 grep --null-data --quiet '[12].2' ; echo $? 0 $ seq 2 | env LC_ALL=en_US.iso88591 grep --null-data --quiet '[1-2].2' ; echo $? 1 grep depends on regex for only last case to support collating element, but regex is not support to substitute NUL for LF as newline character with --null-data.
