| /* Unicode bidi/shaping properties file format --------------------------------- |
| |
| The file format prepared and written here contains several data |
| structures that store indexes or data. |
| |
| Before the data contents described below, there are the headers required by |
| the udata API for loading ICU data. Especially, a UDataInfo structure |
| precedes the actual data. It contains platform properties values and the |
| file format version. |
| |
| The following is a description of format version 2.2 . |
| |
| The file contains the following structures: |
| |
| const int32_t indexes[i0] with values i0, i1, ...: |
| (see UBIDI_IX_... constants for names of indexes) |
| |
| i0 indexLength; -- length of indexes[] (UBIDI_IX_TOP) |
| i1 dataLength; -- length in bytes of the post-header data (incl. indexes[]) |
| i2 trieSize; -- size in bytes of the bidi/shaping properties trie |
| i3 mirrorLength; -- length in uint32_t of the bidi mirroring array |
| |
| i4 jgStart; -- first code point with Joining_Group data |
| i5 jgLimit; -- limit code point for Joining_Group data |
| |
| -- i6, i7 new in format version 2.2: |
| i6 jgStart2; -- first code point with Joining_Group data, second range |
| i7 jgLimit2; -- limit code point for Joining_Group data, second range |
| |
| i8..i14 reservedIndexes; -- reserved values; 0 for now |
| |
| i15 maxValues; -- maximum code values for enumerated properties |
| bits 23..16 contain the max value for Joining_Group, |
| otherwise the bits are used like enum fields in the trie word |
| |
| Serialized trie, see utrie2.h; |
| |
| const uint32_t mirrors[mirrorLength]; |
| |
| const uint8_t jgArray[i5-i4]; -- (i5-i4)+(i7-i6) is always a multiple of 4 |
| const uint8_t jgArray2[i7-i6]; -- new in format version 2.2 |
| |
| Trie data word: |
| Bits |
| 15..13 signed delta to bidi mirroring code point |
| (add delta to input code point) |
| 0 no such code point (source maps to itself) |
| -3..-1, 1..3 delta |
| -4 look in mirrors table |
| 12 is mirrored |
| 11 Bidi_Control |
| 10 Join_Control |
| 9.. 8 Bidi_Paired_Bracket_Type(bpt) -- new in format version 2.1 |
| 7.. 5 Joining_Type |
| 4.. 0 BiDi category |
| |
| |
| Mirrors: |
| Stores some of the bidi mirroring data, where each code point maps to |
| at most one other. |
| Most code points do not have a mirroring code point; most that do have a signed |
| delta stored in the trie data value. Only those where the delta does not fit |
| into the trie data are stored in this table. |
| |
| Logically, this is a two-column table with source and mirror code points. |
| |
| Physically, the table is compressed by taking advantage of the fact that each |
| mirror code point is also a source code point |
| (each of them is a mirror of the other). |
| Therefore, both logical columns contain the same set of code points, which needs |
| to be stored only once. |
| |
| The table stores source code points, and also for each the index of its mirror |
| code point in the same table, in a simple array of uint32_t. |
| Bits |
| 31..21 index to mirror code point (unsigned) |
| 20.. 0 source code point |
| |
| The table is sorted by source code points. |
| |
| |
| Joining_Group array: |
| The Joining_Group values do not fit into the 16-bit trie, but the data is also |
| limited to a small range of code points (Arabic and Syriac) and not |
| well compressible. |
| |
| The start and limit code points for the range are stored in the indexes[] |
| array, and the jgArray[] stores a byte for each of these code points, |
| containing the Joining_Group value. |
| |
| All code points outside of this range have No_Joining_Group (0). |
| |
| ICU 54 adds jgArray2[] for a second range. |
| |
| --- Changes in format version 2.2 --- |
| |
| Addition of second range for Joining_Group values (i6, i7), |
| for 10800..10FFF, including Unicode 7.0 10AC0..10AFF Manichaean. |
| |
| --- Changes in format version 2.1 --- |
| |
| Addition of Bidi_Paired_Bracket_Type(bpt) values. |
| (Trie data bits 9..8 were reserved.) |
| |
| --- Changes in format version 2 --- |
| |
| Change from UTrie to UTrie2. |
