Consider using UNICODE NULL symbol '␀' for nulls

Char nullSymbol = '␀'
While the semantics appeal to me, I am not convinced, because this symbol is somewhat hard to read in comparison to ∅
...
Maybe an option override it then? RefTree.Null(displayAs = "␀")
. I can imagine people may want to display it as string "NULL".
