5 UCS overall structure
This chapter describes the overall structure of the universal multi-octet coded character set (hereinafter referred to as "this coded character set") and illustrates it in Figures 1 and 2. The specifications of this structure are given in the following chapters. In GB13000, any eight-bit character is represented by hexadecimal notation from 00 to FF. See Appendix J (reference number). The canonical form of this code word set and its expression method use "a four-dimensional coding space which is represented as a single entity and consists of 12B three-dimensional groups. Note: In this regard, the 8th bit of the most significant eight bits in the canonical form of the abbreviated character is used for internal processing of the device. As long as its value is set to zero within the standard coding character data element rate, each group contains 256 two-dimensional planes. Each of them contains 256 one-dimensional rows, and each row contains 256 word positions. A character is arranged and encoded on a word position in this coding space. Then, it is declared that the glyph is not used. In the stop point, four octets are used to represent each symbol, and the group, plane, row and glyph are indicated accordingly. Since two octets are not enough to contain the symbols on the boundary, and the 32-bit representation is in line with the architecture of modern processing systems, the regular form consists of four octets.
The four-octet regular form can be used as a four-octet coded character set, which is called CS-4. The first plane (the 00 plane in the 00 group) is called the basic script plane. It includes characters commonly used in alphabetic characters, syllables and ideographic characters. And various symbol numbers. BMF also has a restricted use (RUJ) area, in which symbols have special properties. The planes that follow are considered auxiliary planes or special planes, used to accommodate attached graphic symbols. The 32 planes with plane octet values E0-FF in group 00 are special planes. The 32 groups with group octet values 60~7F in this coded character set are special groups. GB13000 does not specify the content of the character bits in the special area. Each character is arranged in this coded character set according to its group octet, plane octet, row octet, and character octet. In addition to the regular form, The national standard also specifies a double-octet BMP format. Therefore, this multi-language plane can be used as a double-octet coded character set, marked as UCS.2.
GB13000.1-93
In order to give a vocabulary of graphic characters, it is called using a subset of the coding space. Appendix G (reference) specifies a transformation format of UCS (UTF-1), which can be used to transmit text data in communication systems that are sensitive to the octet values of control characters encoded according to the (B2311 structure). 6 Basic structure and terminology

In the code table representing the plane content (such as Figure 2), the horizontal axis should represent the lowest octet, and the left octet has the smallest value; while the vertical axis should represent the higher octet, and the top octet has the smallest value. Each axis in the coding space should be encoded with an octet. In each octet, the highest bit should be the 8th bit, and the lowest bit should be the 1st bit.

The specification of this structure is given in the following chapters. In GB13000, any eight-bit character is represented in hexadecimal notation from 00 to FF. See Appendix J (reference number). The canonical form of this code word set and its expression method use "a four-dimensional coding space which is represented as a single entity and consists of 12B three-dimensional groups.

As long as its value is set to zero within the standard coding character data element rate, each group contains 256 two-dimensional planes. Each of them contains 256 one-dimensional rows, and each row contains 256 word positions. A character is arranged and encoded on a word position in this coding space. Then, it is declared that the glyph is not used. In the stop point, four octets are used to represent each symbol, and the group, plane, row and glyph are indicated accordingly. Since two octets are not enough to contain the symbols on the boundary, and the 32-bit representation is in line with the architecture of modern processing systems, the regular form consists of four octets.
The four-octet regular form can be used as a four-octet coded character set, which is called CS-4. The first plane (the 00 plane in the 00 group) is called the basic script plane.

The 32 groups with group octet values 60~7F in this coded character set are special groups. GB13000 does not specify the content of the character bits in the special area. Each character is arranged in this coded character set according to its group octet, plane octet, row octet, and character octet. In addition to the regular form, The national standard also specifies a double-octet BMP format. Therefore, this multi-language plane can be used as a double-octet coded character set, marked as UCS.2.

5 UCS overall structure
This chapter describes the overall structure of the universal multi-octet coded character set (hereinafter referred to as "this coded character set") and illustrates it in Figures 1 and 2. The specifications of this structure are given in the following chapters. In GB13000, any eight-bit character is represented by hexadecimal notation from 00 to FF. See Appendix J (reference number). The canonical form of this code word set and its expression method use "a four-dimensional coding space which is represented as a single entity and consists of 12B three-dimensional groups. Note: In this regard, the 8th bit of the most significant eight bits in the canonical form of the abbreviated character is used for internal processing of the device. As long as its value is set to zero within the standard coding character data element rate, each group contains 256 two-dimensional planes. Each of them contains 256 one-dimensional rows, and each row contains 256 word positions. A character is arranged and encoded on a word position in this coding space. Then, it is declared that the glyph is not used. In the stop point, four octets are used to represent each symbol, and the group, plane, row and glyph are indicated accordingly. Since two octets are not enough to contain the symbols on the boundary, and the 32-bit representation is in line with the architecture of modern processing systems, the regular form consists of four octets.
The four-octet regular form can be used as a four-octet coded character set, which is called CS-4. The first plane (the 00 plane in the 00 group) is called the basic script plane. It includes characters commonly used in alphabetic characters, syllables and ideographic characters. And various symbol numbers. BMF also has a restricted use (RUJ) area, in which symbols have special properties. The planes that follow are considered auxiliary planes or special planes, used to accommodate attached graphic symbols. The 32 planes with plane octet values E0-FF in group 00 are special planes. The 32 groups with group octet values 60~7F in this coded character set are special groups. GB13000 does not specify the content of the character bits in the special area. Each character is arranged in this coded character set according to its group octet, plane octet, row octet, and character octet. In addition to the regular form, The national standard also specifies a double-octet BMP format. Therefore, this multi-language plane can be used as a double-octet coded character set, marked as UCS.2.

In order to give a vocabulary of graphic characters, it is called using a subset of the coding space.

5 UCS overall structure
This chapter describes the overall structure of the universal multi-octet coded character set (hereinafter referred to as "this coded character set") and illustrates it in Figures 1 and 2. The specifications of this structure are given in the following chapters. In GB13000, any eight-bit character is represented by hexadecimal notation from 00 to FF. See Appendix J (reference number). The canonical form of this code word set and its expression method use "a four-dimensional coding space which is represented as a single entity and consists of 12B three-dimensional groups. Note: In this regard, the 8th bit of the most significant eight bits in the canonical form of the abbreviated character is used for internal processing of the device. As long as its value is set to zero within the standard coding character data element rate, each group contains 256 two-dimensional planes. Each of them contains 256 one-dimensional rows, and each row contains 256 word positions. A character is arranged and encoded on a word position in this coding space. Then, it is declared that the glyph is not used. In the stop point, four octets are used to represent each symbol, and the group, plane, row and glyph are indicated accordingly. Since two octets are not enough to contain the symbols on the boundary, and the 32-bit representation is in line with the architecture of modern processing systems, the regular form consists of four octets.
The four-octet regular form can be used as a four-octet coded character set, which is called CS-4. The first plane (the 00 plane in the 00 group) is called the basic script plane. It includes characters commonly used in alphabetic characters, syllables and ideographic characters. And various symbol numbers. BMF also has a restricted use (RUJ) area, in which symbols have special properties. The planes that follow are considered auxiliary planes or special planes, used to accommodate attached graphic symbols. The 32 planes with plane octet values E0-FF in group 00 are special planes. The 32 groups with group octet values 60~7F in this coded character set are special groups. GB13000 does not specify the content of the character bits in the special area. Each character is arranged in this coded character set according to its group octet, plane octet, row octet, and character octet. In addition to the regular form, The national standard also specifies a double-octet BMP format. Therefore, this multi-language plane can be used as a double-octet coded character set, marked as UCS.2.
GB13000.1-93
In order to give a vocabulary of graphic characters, it is called using a subset of the coding space. Appendix G (reference) specifies a transformation format of UCS (UTF-1), which can be used to transmit text data in communication systems that are sensitive to the octet values of control characters encoded according to the (B2311 structure). 6 Basic structure and terminology
