"The following table gives the default math keywords, their target characters and codes along with spacing and linear-format build-up properties."
Omitted from the original table are operands, enclosures, spaces, big/long variants, and non-NFKC characters. Three characters that default to their emoji variants on iOS, and one related character, are excised.
