427 character can be derived from the font used to display the

428 characters.) If unspecified, defaults to the dimension

|

433 'final Final byte of ISO 2022 escape sequence. Must be

434 supplied. Each combination of (DIMENSION, CHARS) defines a

435 separate namespace for final bytes. Note that ISO

440 character sets.

443 a font whose registry is ISO8859-1, the left half
|
|
|
444 (octets 0x20 - 0x7F) is the `ascii' character set, while
|
|
|
445 the right half (octets 0xA0 - 0xFF) is the `latin-1'
|

446 character set. With 'graphic set to 0, the octets
