2.9.279 SttbfBkmk

  • Article

The SttbfBkmk structure is an STTB structure whose strings specify the names of bookmarks in the document. The cData field size of this STTB structure is 2 bytes. The strings of this STTB contain extended (2-byte) characters, and there is no extra data appended to them—in other words, it is equivalent to an SttbfBkmkBPRepairs structure. The names in this table that begin with the Unicode character 0x005F correspond to hidden bookmarks. The strings in this table MUST be greater than 0 and less than 40 characters in length. The strings in this table MUST be unique, and there MUST NOT be more than 0x3FFB of them.

The SttbfBkmk structure is an STTB structure with the following additional restrictions on its field values:

fExtend (2 bytes): MUST be 0xFFFF.

cData (2 bytes): MUST NOT exceed 0x3FFC.

cbExtra (2 bytes): MUST be 0.

cchData (2 bytes): MUST NOT exceed 40.

Data (variable): For the purpose of achieving the correct definition of "skip character", the following constraints MUST be evaluated using delayed evaluation and examination of characters in a string MUST take place in first-to-last order. Delayed evaluation requires that each constraint not be read until the result of that constraint is needed. For example, application of the following algorithm to the string "Abc" will never require reading of the constraints defining a single byte Katakana character.

To be a valid member of SttbfBkmk, all characters in the string that are not preceded by a skip character SHOULD<243> meet all of the following constraints:

  • Is the first character of the name and satisfies all of the following constraints:

    • Is not Unicode character 0x3000.

    • Is not a double-byte digit, meaning that it is between 0xFF10 and 0xFF19, inclusive.

    • Is one of the following:

      • An alpha character, as defined later.

      • The hidden bookmark character, 0x005F.

      • A single-byte Katakana character, meaning that it is between 0xFF61 and 0xFF9F, inclusive.

      • A far-east, double-byte text character as defined later.

  • Is not the first character of the name and satisfies all of the following constraints:

    • Is not Unicode character 0x3000.

    • Is one of the following:

      • An East Asian, double-byte text character as defined later.

      • An alpha character as defined later.

      • A digit character as defined later.
