153 /* Composite characters are characters constructed by overstriking two
154 or more regular characters.
156 1) The old Mule implementation involves storing composite characters
157 in a buffer as a tag followed by all of the actual characters
158 used to make up the composite character. I think this is a bad
159 idea; it greatly complicates code that wants to handle strings
160 one character at a time because it has to deal with the possibility
161 of great big ungainly characters. It's much more reasonable to
162 simply store an index into a table of composite characters.
164 2) The current implementation only allows for 16,384 separate
165 composite characters over the lifetime of the XEmacs process.
166 This could become a potential problem if the user
167 edited lots of different files that use composite characters.
168 Due to FSF bogosity, increasing the number of allowable
169 composite characters under Mule would decrease the number
170 of possible faces that can exist. Mule already has shrunk
171 this to 2048, and further shrinkage would become uncomfortable.
172 No such problems exist in XEmacs.
174 Composite characters could be represented as 0x80 C1 C2 C3,
175 where each C[1-3] is in the range 0xA0 - 0xFF. This allows
176 for slightly under 2^20 (one million) composite characters
177 over the XEmacs process lifetime, and you only need to
178 increase the size of a Mule character from 19 to 21 bits.
179 Or you could use 0x80 C1 C2 C3 C4, allowing for about
180 85 million (slightly over 2^26) composite characters. */

647 'short-name Short version of the charset name (ex: Latin-1)
648 'long-name Long version of the charset name (ex: ISO8859-1 (Latin-1))
649 'registry A regular expression matching the font registry field for
651 'dimension Number of octets used to index a character in this charset.
652 Either 1 or 2. Defaults to 1.
653 'columns Number of columns used to display a character in this charset.
654 Only used in TTY mode. (Under X, the actual width of a
655 character can be derived from the font used to display the
656 characters.) If unspecified, defaults to the dimension
657 (this is almost always the correct value).
658 'chars Number of characters in each dimension (94 or 96).
659 Defaults to 94. Note that if the dimension is 2, the
660 character set thus described is 94x94 or 96x96.
661 'final Final byte of ISO 2022 escape sequence. Must be
662 supplied. Each combination of (DIMENSION, CHARS) defines a
663 separate namespace for final bytes. Note that ISO
664 2022 restricts the final byte to the range
665 0x30 - 0x7E if dimension == 1, and 0x30 - 0x5F if
666 dimension == 2. Note also that final bytes in the range
667 0x30 - 0x3F are reserved for user-defined (not official)
669 'graphic 0 (use left half of font on output) or 1 (use right half
670 of font on output). Defaults to 0. For example, for
671 a font whose registry is ISO8859-1, the left half
672 (octets 0x20 - 0x7F) is the `ascii' character set, while
673 the right half (octets 0xA0 - 0xFF) is the `latin-1'
674 character set. With 'graphic set to 0, the octets
675 will have their high bit cleared; with it set to 1,
676 the octets will have their high bit set.
677 'direction 'l2r (left-to-right) or 'r2l (right-to-left).
679 'ccl-program A compiled CCL program used to convert a character in
680 this charset into an index into the font. This is in
681 addition to the 'graphic property. The CCL program
682 is passed the octets of the character, with the high
683 bit cleared and set depending upon whether the value
