149 or more regular characters.
|
|
|
150
|
|
|
151 1) The old Mule implementation involves storing composite characters
|
|
|
152 in a buffer as a tag followed by all of the actual characters
|
|
|
153 used to make up the composite character. I think this is a bad
|
|
|
154 idea; it greatly complicates code that wants to handle strings
|
|
|
155 one character at a time because it has to deal with the possibility
|
|
|
156 of great big ungainly characters. It's much more reasonable to
|
|
|
157 simply store an index into a table of composite characters.
|
|
|
158
|
|
|
159 2) The current implementation only allows for 16,384 separate
|
|
|
160 composite characters over the lifetime of the XEmacs process.
|
|
|
161 This could become a potential problem if the user
|
|
|
162 edited lots of different files that use composite characters.
|
|
|
163 Due to FSF bogosity, increasing the number of allowable
|
|
|
164 composite characters under Mule would decrease the number
|
|
|
165 of possible faces that can exist. Mule already has shrunk
|
|
|
166 this to 2048, and further shrinkage would become uncomfortable.
|
|
|
167 No such problems exist in XEmacs.
|
|
|
168
|
|
|
169 Composite characters could be represented as 0x80 C1 C2 C3,
|
|
|
170 where each C[1-3] is in the range 0xA0 - 0xFF. This allows
|
|
|
171 for slightly under 2^20 (one million) composite characters
|
|
|
172 over the XEmacs process lifetime, and you only need to
|
|
|
173 increase the size of a Mule character from 19 to 21 bits.
|
|
|
174 Or you could use 0x80 C1 C2 C3 C4, allowing for about
|
|
|
175 85 million (slightly over 2^26) composite characters. */

622
|
|
|
623 'registry A regular expression matching the font registry field for
|
|
|
624 this character set.
|
|
|
625 'dimension Number of octets used to index a character in this charset.
|
|
|
626 Either 1 or 2. Defaults to 1.
|
|
|
627 'columns Number of columns used to display a character in this charset.
|
|
|
628 Only used in TTY mode. (Under X, the actual width of a
|
|
|
629 character can be derived from the font used to display the
|
|
|
630 characters.) If unspecified, defaults to the dimension
|
|
|
631 (this is almost always the correct value).
|
|
|
632 'chars Number of characters in each dimension (94 or 96).
|
|
|
633 Defaults to 94. Note that if the dimension is 2, the
|
|
|
634 character set thus described is 94x94 or 96x96.
|
|
|
635 'final Final byte of ISO 2022 escape sequence. Must be
|
|
|
636 supplied. Each combination of (DIMENSION, CHARS) defines a
|
|
|
637 separate namespace for final bytes. Note that ISO
|
|
|
638 2022 restricts the final byte to the range
|
|
|
639 0x30 - 0x7E if dimension == 1, and 0x30 - 0x5F if
|
|
|
640 dimension == 2. Note also that final bytes in the range
|
|
|
641 0x30 - 0x3F are reserved for user-defined (not official)
|
|
|
642 character sets.
|
|
|
643 'graphic 0 (use left half of font on output) or 1 (use right half
|
|
|
644 of font on output). Defaults to 0. For example, for
|
|
|
645 a font whose registry is ISO8859-1, the left half
|
|
|
646 (octets 0x20 - 0x7F) is the `ascii' character set, while
|
|
|
647 the right half (octets 0xA0 - 0xFF) is the `latin-1'
|
|
|
648 character set. With 'graphic set to 0, the octets
|
|
|
649 will have their high bit cleared; with it set to 1,
|
|
|
650 the octets will have their high bit set.
|
|
|
651 'direction 'l2r (left-to-right) or 'r2l (right-to-left).
|
|
|
652 Defaults to 'l2r.
|
|
|
653 'ccl-program A compiled CCL program used to convert a character in
|
|
|
654 this charset into an index into the font. This is in
|
|
|
655 addition to the 'graphic property. The CCL program
|
|
|
656 is passed the octets of the character, with the high
|
|
|
657 bit cleared and set depending upon whether the value

658 of the 'graphic property is 0 or 1.
