* 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.
