// Unicode character groups.
 
// The codes get split into ranges of 16-bit codes
// and ranges of 32-bit codes.  It would be simpler
// to use only 32-bit ranges, but these tables are large
// enough to warrant extra care.
//
// Using just 32-bit ranges gives 27 kB of data.
// Adding 16-bit ranges gives 18 kB of data.
// Adding an extra table of 16-bit singletons would reduce
// to 16.5 kB of data but make the data harder to use;
// we don't bother.
