156 /* Composite characters are characters constructed by overstriking two
157 or more regular characters.
159 1) The old Mule implementation involves storing composite characters
160 in a buffer as a tag followed by all of the actual characters
161 used to make up the composite character. I think this is a bad
162 idea; it greatly complicates code that wants to handle strings
163 one character at a time because it has to deal with the possibility
164 of great big ungainly characters. It's much more reasonable to
165 simply store an index into a table of composite characters.
167 2) The current implementation only allows for 16,384 separate
168 composite characters over the lifetime of the XEmacs process.
169 This could become a potential problem if the user
170 edited lots of different files that use composite characters.
171 Due to FSF bogosity, increasing the number of allowable
172 composite characters under Mule would decrease the number
173 of possible faces that can exist. Mule already has shrunk
174 this to 2048, and further shrinkage would become uncomfortable.
175 No such problems exist in XEmacs.
177 Composite characters could be represented as 0x80 C1 C2 C3,
178 where each C[1-3] is in the range 0xA0 - 0xFF. This allows
179 for slightly under 2^20 (one million) composite characters
180 over the XEmacs process lifetime, and you only need to
181 increase the size of a Mule character from 19 to 21 bits.
182 Or you could use 0x80 C1 C2 C3 C4, allowing for about
183 85 million (slightly over 2^26) composite characters. */

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