this character set.
'dimension Number of octets used to index a character in this charset.
Either 1 or 2. Defaults to 1.
+ If UTF-2000 feature is enabled, 3 or 4 are also available.
'columns Number of columns used to display a character in this charset.
Only used in TTY mode. (Under X, the actual width of a
character can be derived from the font used to display the
'chars Number of characters in each dimension (94 or 96).
Defaults to 94. Note that if the dimension is 2, the
character set thus described is 94x94 or 96x96.
+ If UTF-2000 feature is enabled, 128 or 256 are also available.
'final Final byte of ISO 2022 escape sequence. Must be
supplied. Each combination of (DIMENSION, CHARS) defines a
separate namespace for final bytes. Note that ISO
is passed the octets of the character, with the high
bit cleared and set depending upon whether the value
of the 'graphic property is 0 or 1.
+'mother [UTF-2000 only] Base coded-charset.
