421 'long-name Long version of the charset name (ex: ISO8859-1 (Latin-1))

423 this character set.

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

|
429 characters.) If unspecified, defaults to the dimension
|

430 (this is almost always the correct value).
|
|

431 'chars Number of characters in each dimension (94 or 96).
|

432 Defaults to 94. Note that if the dimension is 2, the

433 character set thus described is 94x94 or 96x96.

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

435 supplied. Each combination of (DIMENSION, CHARS) defines a
|
|
|
436 separate namespace for final bytes. Note that ISO

440 0x30 - 0x3F are reserved for user-defined (not official)

441 character sets.
|

442 'graphic 0 (use left half of font on output) or 1 (use right half
|

443 of font on output). Defaults to 0. For example, for
|
|
|
444 a font whose registry is ISO8859-1, the left half
|
|
|
445 (octets 0x20 - 0x7F) is the `ascii' character set, while
|
|
|
446 the right half (octets 0xA0 - 0xFF) is the `latin-1'
|
|

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