I don't know, should you? If the goal is to map it to ISO 8859-1, then
it looks like
function isLatin1 (C : Wide_Character) return Boolean is
return (C < 16#100#);
That is, include C0 and C1, since they are a part of ISO 8859-1. But
without knowing what you want to do with it, I can't say that that's
the right answer.
