2.2 Conformance of devices A device is in conformance with this part of ISO/IEC 8859 if it conforms to the requirements of 2.2.1, and either or both of 2.2.2 and 2.2.3. A claim of conformance shall identify the document which contains the description specified in 2.2.1.
2.2.1 Device description A device that conforms to this part of ISO/IEC 8859 shall be the subject of a description that identifies the means by which the user may supply characters to the device, or may recognize them when they are made available to him, as specified respectively in 2.2.2 and 2.2.3.
2.2.2 Originating devices An originating device shall allow its user to supply any sequence of characters from those specified in clause 6, and shall be capable of transmitting their coded representations within a CC-data-element.
2.2.3 Receiving devices A receiving device shall be capable of receiving and interpreting any coded representations of characters that are within a CC-data-element, and that conform to clause 6, and shall make the corresponding characters available to its user in such a way that the user can identify them from among those specified there, and can distinguish them from each other.

4 Definitions For the purposes of this part of ISO/IEC 8859 the following detinitions apply:
4.1 bit combination: An ordered set of bits used for the representation of characters.
4.2 byte: A bit string that is operated upon as a unit.
4.3 character: A member of a set of elements used for the organization, control, or representation of data. .
4.4 code table: A table showing the characters allocated to each bit combination in a code.
4.5 coded character set; code: A set of unambiguous rules that establishes a character set and the one-to-one relationship between the characters of the set and their bit combinations.
4.6 coded-character-data-element (CC-data- element): An element of interchanged information that is specified to consist of a sequence of coded representations of characters, in accordance with one or more identified standards for coded character sets.
4.7 graphic character: A character, other than a control function, that has a visual representation normally handwritten, printed or displayed, and that has a coded representation consisting of one or more bit combinations. NOTE一In ISO/IEC 8859 a single bit combination is used to represent each character.
4.8 graphic symbol; A visual representation of a graphic character or of a control function. 4.9 position: That part of a code table identified by its column and row coordinates.
