systemd does not work with escaped paths

[Nyyr]

Cannot start systemd service using paths with spaces:

systemd unit file content:
[Unit]
Description=LocalView UPS monitoring service

[Service]
Type=forking
WorkingDirectory=/usr-Socomec\x20UPS-LocalView
ExecStart=/usr-Socomec\x20UPS-LocalView-StartApp.sh

[Install]
WantedBy=multi-user.target

Although systemd-escape converts "/usr/Socomec UPS/LocalView" path to usr-Socomec\x20UPS-LocalView,
systemd complains it is not an absolute path when the '/' in front of it is missing in the unit file:

systemd[1]: /etc/systemd/system/localview.service:6: Working directory path 'usr-Socomec\x20UPS-LocalView' is not absolute.

The same applies for ExecStart entry.

When the syntax check was satisfied I tried to run the service:

systemd[11574]: localview.service: Changing to the requested working directory failed: No such file or directory
systemd[11574]: localview.service: Failed at step CHDIR spawning /usr-Socomec UPS-LocalView-StartApp.sh: No such file or directory

# ll "/usr/Socomec UPS/LocalView/StartApp.sh"
-rwx--x--x 1 root root 220 kvě 26 17:27 '/usr/Socomec UPS/LocalView/StartApp.sh'*

Unescaped path in the unit file obviously does not work either.
