The child's node - is the next node in the vector. - (2) The 0x4000 bits of f0 is spare. - (3) The 0x3f00 bits of f0 contain the character type; this is a number - defined by the enumeration in ucp.h (e.g. ucp_Lu). - (4) The bottom 8 bits of f0 contain the most significant byte of the - character's 24-bit codepoint. - -(f1) (1) The f1 field contains the two least significant bytes of the - codepoint. - -(f2) (1) The 0xf000 bits of f2 contain zero if there is no right child of this - node. Otherwise, they contain one plus the exponent of the power of - two of the offset to the right node (e.g. a value of 3 means 8).
