K3UnicodeSet
This class represents a UnicodeSet and allows to quickly test if a code point is contained in this uset.
The in-memory representation is a non-negated union of codepoint ranges.
Parameters
ranges
The ascendingly-sorted, non-overlapping list of code point ranges. All ranges must be a subset of the range [0x0, 0x10FFFF] and may not be empty. A range may also represent a single code point, in which case the range is equivalent to [codepoint, codepoint).
