As per systemd.unit(5),

*Valid unit names consist of a "name prefix" and a dot and a suffix
specifying the unit type. The "unit prefix" must consist of one or more
valid characters (ASCII letters, digits, ":", "-", "_", ".", and "\").*

Anything else goes through C-style escaping (see systemd-escape) before it
even leaves systemctl.
