But they aren't the same thing; I already showed that.  "t" with
diaeresis matches lower and so (w/nocase lower), but it does not match
(w/nocase upper).  Nor do the mathematical capital letters, which match
upper and so (w/nocase upper), match (w/nocase lower).  By my count there
are 1259 L& characters like this, so your three expressions match three
different sets.

I think the tangent on what Unicode should or should not have done has
distracted us from the original point.  My recommendation is either
to add "title" explicitly (only 31 characters) or else just forget the
whole thing.
