  36  * StringPrep profile file format ------------------------------------
  37  *
  38  * The file format prepared and written here contains a 16-bit trie and a mapping table.
  39  *
  40  * Before the data contents described below, there are the headers required by
  41  * the udata API for loading ICU data. Especially, a UDataInfo structure
  42  * precedes the actual data. It contains platform properties values and the
  43  * file format version.
  44  *
  45  * The following is a description of format version 2.
  46  *
  47  * Data contents:
  48  *
  49  * The contents is a parsed, binary form of RFC3454 and possibly
  50  * NormalizationCorrections.txt depending on the options specified on the profile.
  51  *
  52  * Any Unicode code point from 0 to 0x10ffff can be looked up to get
  53  * the trie-word, if any, for that code point. This means that the input
  54  * to the lookup are 21-bit unsigned integers, with not all of the
  55  * 21-bit range used.
  56  *
  57  * *.spp files customarily begin with a UDataInfo structure, see udata.h and .c.
  58  * After that there are the following structures:
  59  *
  60  * int32_t indexes[_SPREP_INDEX_TOP];           -- _SPREP_INDEX_TOP=16, see enum in sprpimpl.h file
  61  *
  62  * UTrie stringPrepTrie;                        -- size in bytes=indexes[_SPREP_INDEX_TRIE_SIZE]
  63  *
  64  * uint16_t mappingTable[];                     -- Contains the sequecence of code units that the code point maps to
  65  *                                                 size in bytes = indexes[_SPREP_INDEX_MAPPING_DATA_SIZE]
  66  *
  67  * The indexes array contains the following values:
  68  *  indexes[_SPREP_INDEX_TRIE_SIZE]                  -- The size of the StringPrep trie in bytes
  69  *  indexes[_SPREP_INDEX_MAPPING_DATA_SIZE]          -- The size of the mappingTable in bytes
  70  *  indexes[_SPREP_NORM_CORRECTNS_LAST_UNI_VERSION]  -- The index of Unicode version of last entry in NormalizationCorrections.txt
  71  *  indexes[_SPREP_ONE_UCHAR_MAPPING_INDEX_START]    -- The starting index of 1 UChar  mapping index in the mapping table
  72  *  indexes[_SPREP_TWO_UCHARS_MAPPING_INDEX_START]   -- The starting index of 2 UChars mapping index in the mapping table
  73  *  indexes[_SPREP_THREE_UCHARS_MAPPING_INDEX_START] -- The starting index of 3 UChars mapping index in the mapping table
  74  *  indexes[_SPREP_FOUR_UCHARS_MAPPING_INDEX_START]  -- The starting index of 4 UChars mapping index in the mapping table
  75  *  indexes[_SPREP_OPTIONS]                          -- Bit set of options to turn on in the profile, e.g: USPREP_NORMALIZATION_ON, USPREP_CHECK_BIDI_ON
  76  *
  77  *
  78  * StringPrep Trie :
  79  *
  80  * The StringPrep tries is a 16-bit trie that contains data for the profile.
  81  * Each code point is associated with a value (trie-word) in the trie.
  82  *
  83  * - structure of data words from the trie
  84  *
  85  *  i)  A value greater than or equal to _SPREP_TYPE_THRESHOLD (0xFFF0)
  86  *      represents the type associated with the code point
  87  *      if(trieWord >= _SPREP_TYPE_THRESHOLD){
  88  *          type = trieWord - 0xFFF0;
  89  *      }
  90  *      The type can be :
  91  *             USPREP_UNASSIGNED
  92  *             USPREP_PROHIBITED
  93  *             USPREP_DELETE
  94  *
  95  *  ii) A value less than _SPREP_TYPE_THRESHOLD means the type is USPREP_MAP and
  96  *      contains distribution described below
  97  *
  98  *      0       -  ON : The code point is prohibited (USPREP_PROHIBITED). This is to allow for codepoint that are both prohibited and mapped.
  99  *      1       -  ON : The value in the next 14 bits is an index into the mapping table
 100  *                 OFF: The value in the next 14 bits is an delta value from the code point
 101  *      2..15   -  Contains data as described by bit 1. If all bits are set
 102  *                 (value = _SPREP_MAX_INDEX_VALUE) then the type is USPREP_DELETE
 103  *
 104  *
 105  * Mapping Table:
 106  * The data in mapping table is sorted according to the length of the mapping sequence.
 107  * If the type of the code point is USPREP_MAP and value in trie word is an index, the index
 108  * is compared with start indexes of sequence length start to figure out the length according to
 109  * the following algorithm:
 110  *
 111  *              if(       index >= indexes[_SPREP_ONE_UCHAR_MAPPING_INDEX_START] &&
 112  *                        index < indexes[_SPREP_TWO_UCHARS_MAPPING_INDEX_START]){
 113  *                   length = 1;
 114  *               }else if(index >= indexes[_SPREP_TWO_UCHARS_MAPPING_INDEX_START] &&
 115  *                        index < indexes[_SPREP_THREE_UCHARS_MAPPING_INDEX_START]){
 116  *                   length = 2;
 117  *               }else if(index >= indexes[_SPREP_THREE_UCHARS_MAPPING_INDEX_START] &&
 118  *                        index < indexes[_SPREP_FOUR_UCHARS_MAPPING_INDEX_START]){
 119  *                   length = 3;
 120  *               }else{
 121  *                   // The first position in the mapping table contains the length
 122  *                   // of the sequence
 123  *                   length = mappingTable[index++];
 124  *
 125  *               }
