416 /* Composite characters are characters constructed by overstriking two
417 or more regular characters.
419 1) The old Mule implementation involves storing composite characters
420 in a buffer as a tag followed by all of the actual characters
421 used to make up the composite character. I think this is a bad
422 idea; it greatly complicates code that wants to handle strings
423 one character at a time because it has to deal with the possibility
424 of great big ungainly characters. It's much more reasonable to
425 simply store an index into a table of composite characters.
427 2) The current implementation only allows for 16,384 separate
428 composite characters over the lifetime of the XEmacs process.
429 This could become a potential problem if the user
430 edited lots of different files that use composite characters.
431 Due to FSF bogosity, increasing the number of allowable
432 composite characters under Mule would decrease the number
433 of possible faces that can exist. Mule already has shrunk
434 this to 2048, and further shrinkage would become uncomfortable.
435 No such problems exist in XEmacs.
437 Composite characters could be represented as 0x80 C1 C2 C3,
438 where each C[1-3] is in the range 0xA0 - 0xFF. This allows
439 for slightly under 2^20 (one million) composite characters
440 over the XEmacs process lifetime, and you only need to
441 increase the size of a Mule character from 19 to 21 bits.
442 Or you could use 0x80 C1 C2 C3 C4, allowing for about
443 85 million (slightly over 2^26) composite characters. */

1184 'short-name Short version of the charset name (ex: Latin-1)
1185 'long-name Long version of the charset name (ex: ISO8859-1 (Latin-1))
1186 'registry A regular expression matching the font registry field for
1188 'dimension Number of octets used to index a character in this charset.
1189 Either 1 or 2. Defaults to 1.
1190 'columns Number of columns used to display a character in this charset.
1191 Only used in TTY mode. (Under X, the actual width of a
1192 character can be derived from the font used to display the
1193 characters.) If unspecified, defaults to the dimension
1194 (this is almost always the correct value).
1195 'chars Number of characters in each dimension (94 or 96).
1196 Defaults to 94. Note that if the dimension is 2, the
1197 character set thus described is 94x94 or 96x96.
1198 'final Final byte of ISO 2022 escape sequence. Must be
1199 supplied. Each combination of (DIMENSION, CHARS) defines a
1200 separate namespace for final bytes. Note that ISO
1201 2022 restricts the final byte to the range
1202 0x30 - 0x7E if dimension == 1, and 0x30 - 0x5F if
1203 dimension == 2. Note also that final bytes in the range
1204 0x30 - 0x3F are reserved for user-defined (not official)
1206 'graphic 0 (use left half of font on output) or 1 (use right half
1207 of font on output). Defaults to 0. For example, for
1208 a font whose registry is ISO8859-1, the left half
1209 (octets 0x20 - 0x7F) is the `ascii' character set, while
1210 the right half (octets 0xA0 - 0xFF) is the `latin-1'
1211 character set. With 'graphic set to 0, the octets
1212 will have their high bit cleared; with it set to 1,
1213 the octets will have their high bit set.

1216 'ccl-program A compiled CCL program used to convert a character in
1217 this charset into an index into the font. This is in
1218 addition to the 'graphic property. The CCL program
1219 is passed the octets of the character, with the high
1220 bit cleared and set depending upon whether the value
1221 of the 'graphic property is 0 or 1.
