/*
* ### TODO ICU 2.4 markus Ideas for getting properties-unique code point ranges:
*
* To enumerate properties efficiently, one needs to know ranges of
* repetitive values, so that the value of only each start code point
* can be applied to the whole range.
* This information is in principle available in the uprops.icu data.
*
* There are two obstacles:
*
* 1. Some properties are computed from multiple data structures,
* making it necessary to get repetitive ranges by intersecting
* ranges from multiple tries.
*
* 2. It is not economical to write code for getting repetitive ranges
* that are precise for each of some 50 properties.
*
* Compromise ideas:
*
* - Get ranges per trie, not per individual property.
* Each range contains the same values for a whole group of properties.
* This would generate currently five range sets, two for uprops.icu tries
* and three for unorm.icu tries.
*
* - Combine sets of ranges for multiple tries to get sufficient sets
* for properties, e.g., the uprops.icu main and auxiliary tries
* for all non-normalization properties.
*
* Ideas for representing ranges and combining them:
*
* - A UnicodeSet could hold just the start code points of ranges.
* Multiple sets are easily combined by or-ing them together.
*
* - Alternatively, a UnicodeSet could hold each even-numbered range.
* All ranges could be enumerated by using each start code point
* (for the even-numbered ranges) as well as each limit (end+1) code point
* (for the odd-numbered ranges).
* It should be possible to combine two such sets by xor-ing them,
* but no more than two.
*
* The second way to represent ranges may(?!) yield smaller UnicodeSet arrays,
* but the first one is certainly simpler and applicable for combining more than
* two range sets.
*
* It is possible to combine all range sets for all uprops/unorm tries into one
* set that can be used for all properties.
* As an optimization, there could be less-combined range sets for certain
* groups of properties.
* The relationship of which less-combined range set to use for which property
* depends on the implementation of the properties and must be hardcoded
* - somewhat error-prone and higher maintenance but can be tested easily
* by building property sets "the simple way" in test code.
