37 { $vocab-link "unicode.categories" } " is a vocabulary which provides predicates for determining if a code point has a particular property, for example being a lower cased letter. These should be used in preference to the " { $vocab-link "ascii" } " equivalents in most cases. Below are links to classes of characters, but note that each of these also has a predicate defined, which is usually more useful."
