-Produces a list of three-element lists, where each three-element list represents a set of consecutive code points for-which the Unicode standard specifies character properties. Each three-element list contains two integers and a boolean; the first integer is a starting code-point value (inclusive), the second integer is an ending code-point value (inclusive), and the boolean is #t when all characters in the code-point range have identical results for all of the character predicates above. The three-element lists are ordered in the overall result list such that later lists represent larger code-point values, and all three-element lists are separated from every other by at least one code-point value that is not specified by Unicode.
