A: INTERSECT appears in the catalog but not UNION

INTERSECT ({a, o, u, ee, ii}, {ee, ii}) ▶ {ee, ii}
union ({a, o, u}, {ee, ii}) ▶ set [a, o, u, ee, ii]

As has symbolic arguments, are CAS commands, then because one is lowercase and uppercase another?, this drawback makes programming is tedious.
output of INTERSECT should be corrected in set[] and I think it must be lowercase, are agree or not.

B: in the history screen displayed in pretty print using Unicode characters ∪, ∩

{a, o, u, ee, ii} ∩ {ee, ii}
{a, o, u} ∪ {ee, ii}
