Character set terms:

Intermediate character: A character whose bit combination occurs between the Escape character and the final character in an escape sequence consisting of more than two bit combinations.

Final character: The character whose bit combination terminates an escape sequence.

Escape sequence: A bit string that is used for control purposes in code extension procedures and that consists of two or more bit combinations, of which the first is the bit combination corresponding to the Escape character.

Bit combination: A sequence of consecutive bits that represents a character.

Character: A member of a set of elements used for the organization, control or representation of data.

Coded character set; code: A set of unambiguous rules that establish a character set and the one-to-one relationships between the characters of the set and their bit combinations.

Code extension: The techniques for encoding characters that are not included in a given coded character set.

Control character: A control function that is coded as a single bit combination.

Control function: An action that affects the recording, processing, transmission or interpretation of data and that has a coded representation consisting of one or more bit combinations.

Escape (ESC): A control character (ASCII 1B16) which is used to provide additional characters by code extension. It alters the meaning of a limited number of contiguously following bit combinations.
