For whatever reason, the OS documentation lacks a list of allowed compose key sequences. But they are intuitive enough that you can find many of them through experimentation. For example:
Musical sharp ("♯"): compose + "#" + "#".
Interrobang ("‽"): compose + "!" + "?".
Letter "ñ" as in "jalapeño": compose + "n" + "~".
Copyright ("ⓒ"): compose + "(" + c + ")".
Oops, I got one wrong.
Copyright("©"): compose + "c" + "o".
The one I had is bigger: Ⓒ vs. ©.
