Dear Maintainer,

    * What led up to the situation?

Calculating checksum on files on an ArchLinux filesystem from Debian

    * What exactly did you do (or not do) that was effective (or
      ineffective)?

sha256sum '/usr/lib/systemd/system/system-systemd\x2dcryptsetup.slice'

    * What was the outcome of this action?

\68dc6e85631e077f2bc751352459823844911b93b7ba2afd95d96c893222bb50  
/usr/lib/systemd/system/system-systemd\\x2dcryptsetup.slice

Notice the first \

That's expected behavior, and distinguishes literal vs escaped back slashes.
If you would like simpler (and more robust) programmatic control of the output,
consider using the --zero option, which does not need this escaping mechanism.
