Imports
java.util.Arrays, .Comparator
Unicode Properties Vectors associated with code point ranges. Rows of primitive integers in a contiguous array 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.

Implements com.ibm.icu.impl.TrieBuilder.DataManipulate.getFoldedValue.

Doc from com.ibm.icu.impl.TrieBuilder.DataManipulate.getFoldedValue.

Build-time trie callback function, used with serialize(). This function calculates a lead surrogate's value including a folding offset from the 1024 supplementary code points [start..start+1024[ . It is U+10000 <= start <= U+10fc00 and (start&0x3ff)==0. The folding offset is provided by the caller. It is offset=UTRIE_BMP_INDEX_LENGTH+n*UTRIE_SURROGATE_BLOCK_COUNT with n=0..1023. Instead of the offset itself, n can be stored in 10 bits - or fewer if it can be assumed that few lead surrogates have associated data. The returned value must be - not zero if and only if there is relevant data for the corresponding 1024 supplementary code points - such that UTrie.getFoldingOffset(UNewTrieGetFoldedValue(..., offset))==offset

Returns:int

a folded value, or 0 if there is no relevant data for the lead surrogate.
