 | | Graphic character sets may be represented by either 8 bits per character, or, where a larger number of characters needs to be accommodated by the character set, by more than 8 bits codes per character (usually in multiples of 8). |
 | | I is the Intermediate character sequence, which may be one or more characters in length and indicates whether the set is designated as the G0 set or the G1 set and whether the set has one byte or multiple bytes per character. |
 | | Escape sequences to designate alternate graphic character sets may occur wherever the alternate characters are needed, e.g., within a word, at the beginning of a subfield, or in the middle of a subfield. |
