Description SHAURYA 2018-10-25 16:32:07 UTC 
Description of problem:

escaped systemd unit retruns wrongly escaped (and different) Id

Version-Release number of selected component (if applicable):

Latest systemd release

How reproducible:

Always

Steps to Reproduce:

Run show all and grep the Id of an escaped unit

[]#  /usr/bin/systemctl --no-pager --all show -- 'systemd-fsck@dev-mapper-vg0\x2dscratch.service' |grep Id=
Id=systemd-fsck@dev-mapper-vg0\x5cx2dscratch.service

--> the extra x5c is the backslash (\) systemd-escape'd

no real issue with systemd-escape
# systemd-escape -u 'systemd-fsck@dev-mapper-vg0\x2dscratch.service'
systemd/fsck@dev/mapper/vg0-scratch.service


on fedora27, it gives the correct Id
 /usr/bin/systemctl --no-pager --all show -- "systemd-fsck@dev-mapper-vg0\x2dscratch.service" |grep Id=
Id=systemd-fsck@dev-mapper-vg0\x2dscratch.service
