The Wikipedia has the following information about this codepoint:
A wedding is a ceremony in which two people are united in marriage. Wedding traditions and customs vary greatly between cultures, ethnicities, races, religions, denominations, countries, social classes, and sexual orientations. Most wedding ceremonies involve an exchange of marriage vows by a couple; a presentation of a gift (e.g., an offering, rings, a symbolic item, flowers, money, or a dress); and a public proclamation of marriage by an authority figure or celebrant. Special wedding garments are often worn, and the ceremony is sometimes followed by a wedding reception. Music, poetry, prayers, or readings from religious texts or literature are also commonly incorporated into the ceremony, as well as superstitious customs.
