Fine, just do it using String; every component of a String
is well defined. Code points have nothing to do with Strings.
Let me try this in Kleene terms, with hypothetical wildcard
meaning (which I think you still have not specified explicitly):
Start with the (terminal) symbol a.
Continue with any number of (terminal) symbols
drawn from Σ (which includes a and ¶, but not *).
End with the terminal symbol ¶.

It does no such thing absent a definition of *.
The important question is what constitues Σ, not L.
If we use String, used in Directories.Start_Search,
then everything, including Σ, is well defined in Ada,
as is.
