A \lstinline[language=grammar]!unit-symbol! is a non-empty string of \lstinline[language=grammar]!unit-char! characters.
The set of allowed characters is currently not defined, but it is recommended to only use \lstinline[language=grammar]!NON-DIGIT!.
These are restricted to \lstinline[language=grammar]!NON-DIGIT! characters.
It is required that basic and derived units of the SI system are recognized, but tools are allowed to additionally support user-defined unit symbols.
The required unit symbols do not make use of Greek letters, but a unit such as $\Omega$ is spelled out as \lstinline!"Ohm"!.
Similarly degree is spelled out as \lstinline!"deg"!, both on its own (for angles) and as part of \lstinline!"degC"!, \lstinline!"degF"! and \lstinline!"degRk"! for temperatures (Celsius, Fahrenheit and Rankine).
