/*
* Unicode Properties Vectors associated with code point ranges.
* Stored in an array of uint32_t.
*
* The array starts with a header, then rows of integers store
* the range limits and the properties vectors.
*
* In each row, row[0] contains the start code point and
* row[1] contains the limit code point,
* which is the start of the next range.
*
* Initially, there is only one range [0..0x110000[ with values 0.
*
* It would be possible to store only one range boundary per row,
* but self-contained rows allow to later sort them by contents.
