Comment # 20 on bug 1076779 from Michael Chang

Weird, it seems "Binary file (standard input) matches" in the "grep -E" output,
but wouldn't  "udevadm info .." outputs plan text ? Could it be locale settings
?

Somehow I could not reproduce the error, would you please help to provide your
"udevinfo -q property -n /dev/sdb2" outputs ?

Also what about result of pipeline ?

2. udevadm info -q property -n /dev/sdb2 | sed -n -e
's/\(.*\)=\(.*\)/\1="\2"/p'
3. udevadm info -q property -n /dev/sdb2 | sed -n -e
's/\(.*\)=\(.*\)/\1="\2"/p' | grep -E
'^(MD_CONTAINER|ID_PART_ENTRY_(TYPE|SCHEME)|PARTNAME)='

Thanks.
