 |  * | 
 |  * ICU 56: New in formatVersion 3 compared with 2: ------------- | 
 |  * | 
 |  * Resource bundles can optionally use shared string-v2 values | 
 |  * stored in the pool bundle. | 
 |  * If so, then the indexes[] contain two new values | 
 |  * in previously-unused bits of existing indexes[] slots: | 
 |  * - poolStringIndexLimit: | 
 |  *     String-v2 offsets (in 32-bit Resource words) below this limit | 
 |  *     point to pool bundle string-v2 values. | 
 |  * - poolStringIndex16Limit: | 
 |  *     Resource16 string-v2 offsets below this limit | 
 |  *     point to pool bundle string-v2 values. | 
 |  * Guarantee: poolStringIndex16Limit <= poolStringIndexLimit | 
 |  * | 
 |  * The local bundle's poolStringIndexLimit is greater than | 
 |  * any pool bundle string index used in the local bundle. | 
 |  * The poolStringIndexLimit should not be greater than | 
 |  * the maximum possible pool bundle string index. | 
 |  * | 
 |  * The maximum possible pool bundle string index is the index to the last non-NUL | 
 |  * pool string character, due to suffix sharing. | 
 |  * | 
 |  * In the pool bundle, there is no structure that lists the strings. | 
 |  * (The root resource is an empty Table.) | 
 |  * If the strings need to be enumerated (as genrb --usePoolBundle does), | 
 |  * then iterate through the pool bundle's 16-bit-units array from the beginning. | 
 |  * Stop at the end of the array, or when an explicit or implicit string length | 
 |  * would lead beyond the end of the array, | 
 |  * or when an apparent string is not NUL-terminated. | 
 |  * (Future genrb version might terminate the strings with | 
 |  * what looks like a large explicit string length.) | 
 |  * | 
 |  * ICU 4.4: New in formatVersion 2 compared with 1.3: ------------- | 
 |  * | 
 |  * Three new resource types -- String-v2, Table16 and Array16 -- have their | 
 |  * values stored in a new array of 16-bit units between the table key strings | 
 |  * and the start of the other resources. | 
 |  * | 
 |  * genrb eliminates duplicates among Unicode string-v2 values. | 
 |  * Multiple Unicode strings may use the same offset and string data, | 
 |  * or a short string may point to the suffix of a longer string. ("Suffix sharing") | 
 |  * For example, one string "abc" may be reused for another string "bc" by pointing | 
 |  * to the second character. (Short strings-v2 are NUL-terminated | 
 |  * and not preceded by an explicit length value.) | 
 |  * | 
 |  * It is allowed for all resource types to share values. | 
 |  * The swapper code (ures_swap()) has been modified so that it swaps each item | 
 |  * exactly once. | 
 |  * | 
 |  * A resource bundle may use a special pool bundle. Some or all of the table key strings | 
 |  * of the using-bundle are omitted, and the key string offsets for such key strings refer | 
 |  * to offsets in the pool bundle. | 
 |  * The using-bundle's and the pool-bundle's indexes[URES_INDEX_POOL_CHECKSUM] values | 
 |  * must match. | 
 |  * Two bits in indexes[URES_INDEX_ATTRIBUTES] indicate whether a resource bundle | 
 |  * is or uses a pool bundle. | 
 |  * | 
 |  * Table key strings must be compared in ASCII order, even if they are not | 
 |  * stored in ASCII. | 
 |  * | 
 |  * New in formatVersion 1.3 compared with 1.2: ------------- | 
 |  * | 
 |  * genrb eliminates duplicates among key strings. | 
 |  * Multiple table items may share one key string, or one item may point | 
 |  * to the suffix of another's key string. ("Suffix sharing") | 
 |  * For example, one key "abc" may be reused for another key "bc" by pointing | 
 |  * to the second character. (Key strings are NUL-terminated.) | 
 |  * | 
 |  * ------------- | 
 |  * | 
 |  * An ICU4C resource bundle file (.res) is a binary, memory-mappable file | 
 |  * with nested, hierarchical data structures. | 
 |  * It physically contains the following: | 
 |  * | 
 |  *   Resource root; -- 32-bit Resource item, root item for this bundle's tree; | 
 |  *                     currently, the root item must be a table or table32 resource item | 
 |  *   int32_t indexes[indexes[0]]; -- array of indexes for friendly | 
 |  *                                   reading and swapping; see URES_INDEX_* above | 
 |  *                                   new in formatVersion 1.1 (ICU 2.8) | 
 |  *   char keys[]; -- characters for key strings | 
 |  *                   (formatVersion 1.0: up to 65k of characters; 1.1: <2G) | 
 |  *                   (minus the space for root and indexes[]), | 
 |  *                   which consist of invariant characters (ASCII/EBCDIC) and are NUL-terminated; | 
 |  *                   padded to multiple of 4 bytes for 4-alignment of the following data | 
 |  *   uint16_t 16BitUnits[]; -- resources that are stored entirely as sequences of 16-bit units | 
 |  *                             (new in formatVersion 2/ICU 4.4) | 
 |  *                             data is indexed by the offset values in 16-bit resource types, | 
 |  *                             with offset 0 pointing to the beginning of this array; | 
 |  *                             there is a 0 at offset 0, for empty resources; | 
 |  *                             padded to multiple of 4 bytes for 4-alignment of the following data | 
 |  *   data; -- data directly and indirectly indexed by the root item; | 
 |  *            the structure is determined by walking the tree | 
 |  * | 
 |  * Each resource bundle item has a 32-bit Resource handle (see typedef above) | 
 |  * which contains the item type number in its upper 4 bits (31..28) and either | 
 |  * an offset or a direct value in its lower 28 bits (27..0). | 
 |  * The order of items is undefined and only determined by walking the tree. | 
 |  * Leaves of the tree may be stored first or last or anywhere in between, | 
 |  * and it is in theory possible to have unreferenced holes in the file. | 
 |  * | 
 |  * 16-bit-unit values: | 
 |  * Starting with formatVersion 2/ICU 4.4, some resources are stored in a special | 
 |  * array of 16-bit units. Each resource value is a sequence of 16-bit units, | 
 |  * with no per-resource padding to a 4-byte boundary. | 
 |  * 16-bit container types (Table16 and Array16) contain Resource16 values | 
 |  * which are offsets to String-v2 resources in the same 16-bit-units array. | 
 |  * | 
 |  * Direct values: | 
 |  * - Empty Unicode strings have an offset value of 0 in the Resource handle itself. | 
 |  * - Starting with formatVersion 2/ICU 4.4, an offset value of 0 for | 
 |  *   _any_ resource type indicates an empty value. | 
 |  * - Integer values are 28-bit values stored in the Resource handle itself; | 
 |  *   the interpretation of unsigned vs. signed integers is up to the application. | 
 |  * | 
 |  * All other types and values use 28-bit offsets to point to the item's data. | 
 |  * The offset is an index to the first 32-bit word of the value, relative to the | 
 |  * start of the resource data (i.e., the root item handle is at offset 0). | 
 |  * To get byte offsets, the offset is multiplied by 4 (or shifted left by 2 bits). | 
 |  * All resource item values are 4-aligned. | 
 |  * | 
 |  * New in formatVersion 2/ICU 4.4: Some types use offsets into the 16-bit-units array, | 
 |  * indexing 16-bit units in that array. | 
 |  * | 
 |  * The structures (memory layouts) for the values for each item type are listed | 
 |  * in the table below. | 
 |  * | 
 |  * Nested, hierarchical structures: ------------- | 
 |  * | 
 |  * Table items contain key-value pairs where the keys are offsets to char * key strings. | 
 |  * The values of these pairs are either Resource handles or | 
 |  * offsets into the 16-bit-units array, depending on the table type. | 
 |  * | 
 |  * Array items are simple vectors of Resource handles, | 
 |  * or of offsets into the 16-bit-units array, depending on the array type. | 
 |  * | 
 |  * Table key string offsets: ------- | 
 |  * | 
 |  * Key string offsets are relative to the start of the resource data (of the root handle), | 
 |  * i.e., the first string has an offset of 4+sizeof(indexes). | 
 |  * (After the 4-byte root handle and after the indexes array.) | 
 |  * | 
 |  * If the resource bundle uses a pool bundle, then some key strings are stored | 
 |  * in the pool bundle rather than in the local bundle itself. | 
 |  * - In a Table or Table16, the 16-bit key string offset is local if it is | 
 |  *   less than indexes[URES_INDEX_KEYS_TOP]<<2. | 
 |  *   Otherwise, subtract indexes[URES_INDEX_KEYS_TOP]<<2 to get the offset into | 
 |  *   the pool bundle key strings. | 
 |  * - In a Table32, the 32-bit key string offset is local if it is non-negative. | 
 |  *   Otherwise, reset bit 31 to get the pool key string offset. | 
 |  * | 
 |  * Unlike the local offset, the pool key offset is relative to | 
 |  * the start of the key strings, not to the start of the bundle. | 
 |  * | 
 |  * An alias item is special (and new in ICU 2.4): -------------- | 
 |  * | 
 |  * Its memory layout is just like for a UnicodeString, but at runtime it resolves to | 
 |  * another resource bundle's item according to the path in the string. | 
 |  * This is used to share items across bundles that are in different lookup/fallback | 
 |  * chains (e.g., large collation data among zh_TW and zh_HK). | 
 |  * This saves space (for large items) and maintenance effort (less duplication of data). | 
 |  * | 
 |  * -------------------------------------------------------------------------- | 
 |  * | 
 |  * Resource types: | 
 |  * | 
 |  * Most resources have their values stored at four-byte offsets from the start | 
 |  * of the resource data. These values are at least 4-aligned. | 
 |  * Some resource values are stored directly in the offset field of the Resource itself. | 
 |  * See UResType in unicode/ures.h for enumeration constants for Resource types. | 
 |  * | 
 |  * Some resources have their values stored as sequences of 16-bit units, | 
 |  * at 2-byte offsets from the start of a contiguous 16-bit-unit array between | 
 |  * the table key strings and the other resources. (new in formatVersion 2/ICU 4.4) | 
 |  * At offset 0 of that array is a 16-bit zero value for empty 16-bit resources. | 
 |  * | 
 |  * Resource16 values in Table16 and Array16 are 16-bit offsets to String-v2 | 
 |  * resources, with the offsets relative to the start of the 16-bit-units array. | 
 |  * Starting with formatVersion 3/ICU 56, if offset<poolStringIndex16Limit | 
 |  * then use the pool bundle's 16-bit-units array, | 
 |  * otherwise subtract that limit and use the local 16-bit-units array. | 
 |  * |
