Constants

• BMP_INDEX_LENGTH
  The length of the BMP index table. 1024=0x400
• CODE_POINT_MAX
• CP_PER_INDEX_2_ENTRY
  Number of code points per index-2 table entry. 512=0x200
• ERROR_VALUE_NEG_DATA_OFFSET
  Offset from dataLength (to be subtracted) for fetching the value returned for out-of-range code points and ill-formed UTF-8/16.

  Number of entries in a data block for code points below the fast limit. 64=0x40
• FAST_TYPE_DATA_MASK
  Mask for getting the lower bits for the in-fast-data-block offset.
• FAST_TYPE_FAST_INDEXING_MAX
  Fast indexing limit for “fast”-type trie
• FAST_TYPE_SHIFT

  Shift size for getting the index-3 table offset.
• SMALL_DATA_BLOCK_LENGTH
  Number of entries in a small data block. 16=0x10
• SMALL_DATA_MASK
