MULTISET UNION
Overview
A union that adds multiplicities rather than discarding them needs its own sign, and U+228E supplies it: the cup of ordinary union with a plus enclosed, indicating that duplicate elements accumulate instead of collapsing. It appears in combinatorics and in formal language theory wherever bags are used in place of sets. Unicode places it in Mathematical Operators with the general category Sm (symbol, math), so renderers space it as a binary operator between its two arguments. The glyph is intentionally close to U+222A UNION, since the notation is meant to signal a variant of that operation rather than an unrelated one.
