A rigorous review process includes offering each NISO voting member and other interested parties an opportunity to review the proposed standard. Further

A Chinese character which basically has the same meaning and pronunciation as the traditional character but has been simplified, usually by means of a reduction in the number of strokes in the graphic. 3.16. Waditional Charact

Simplified characters are also considered variant characters. 4. Implementation and Maintenance of Codes 4.1. The implementation of this Ame

Although sections are logically linear, the matrix divides the linear strip into six columns (see Figure 2). The three-byte value of each graphic character in a matrix is

45、specified by the hexadecimal value of the plane (high-order byte), the hexadecimal value of the section (second-order byte), and the hexadecimal value of the position e 3 Figure 2 Matrix Representation o Section 4C Plane 4B Section 4C 4 (Location of EACC: 4B4C3C) in the matrix (low-order byte). The

46、hexadecimal value of the low-order byte is derived by placing the column number to the left of the row number of the matrix. Decimal 10, 11, 12, 13, 14, and 15 are converted to hexadecimal notation A,B,C,D,E, and F when specifying the low-order byte. 5.4. Layers. To assist in specifying EACC charact

47、ers and preserving the related nature of the coding, the EACC coding space is arranged into “layers” of six planes each. To illustrate the layers, the EACC coding space shown previously as a cube could be reconfigured as shown in Figure 3. The first 12 layers are used to show topological relationshi

They allow the character codes of variant forms of a character to be related to the traditional character in the first layer. 4 NISO Z39.64 89 m 6478908 OOOO - ANSI/NISO 239.64-1989 Figure 3 EACC Layering (PL- PLANE) PL 21 PL 22 PL 23 PL 24 P
