333 /* Composite characters are characters constructed by overstriking two
334 or more regular characters.
336 1) The old Mule implementation involves storing composite characters
337 in a buffer as a tag followed by all of the actual characters
338 used to make up the composite character. I think this is a bad
339 idea; it greatly complicates code that wants to handle strings
340 one character at a time because it has to deal with the possibility
341 of great big ungainly characters. It's much more reasonable to
342 simply store an index into a table of composite characters.
344 2) The current implementation only allows for 16,384 separate
345 composite characters over the lifetime of the XEmacs process.
346 This could become a potential problem if the user
347 edited lots of different files that use composite characters.
348 Due to FSF bogosity, increasing the number of allowable
349 composite characters under Mule would decrease the number
350 of possible faces that can exist. Mule already has shrunk
351 this to 2048, and further shrinkage would become uncomfortable.
352 No such problems exist in XEmacs.
354 Composite characters could be represented as 0x80 C1 C2 C3,
355 where each C[1-3] is in the range 0xA0 - 0xFF. This allows
356 for slightly under 2^20 (one million) composite characters
357 over the XEmacs process lifetime, and you only need to
358 increase the size of a Mule character from 19 to 21 bits.
359 Or you could use 0x80 C1 C2 C3 C4, allowing for about
360 85 million (slightly over 2^26) composite characters. */

1445 'short-name Short version of the charset name (ex: Latin-1)
1446 'long-name Long version of the charset name (ex: ISO8859-1 (Latin-1))
1447 'registry A regular expression matching the font registry field for
1449 'dimension Number of octets used to index a character in this charset.
1450 Either 1 or 2. Defaults to 1.
1451 If UTF-2000 feature is enabled, 3 or 4 are also available.
1452 'columns Number of columns used to display a character in this charset.
1453 Only used in TTY mode. (Under X, the actual width of a
1454 character can be derived from the font used to display the
1455 characters.) If unspecified, defaults to the dimension
1456 (this is almost always the correct value).
1457 'chars Number of characters in each dimension (94 or 96).
1458 Defaults to 94. Note that if the dimension is 2, the
1459 character set thus described is 94x94 or 96x96.
1460 If UTF-2000 feature is enabled, 128 or 256 are also available.
1461 'final Final byte of ISO 2022 escape sequence. Must be
1462 supplied. Each combination of (DIMENSION, CHARS) defines a
1463 separate namespace for final bytes. Note that ISO
1464 2022 restricts the final byte to the range
1465 0x30 - 0x7E if dimension == 1, and 0x30 - 0x5F if
1466 dimension == 2. Note also that final bytes in the range
1467 0x30 - 0x3F are reserved for user-defined (not official)
1469 'graphic 0 (use left half of font on output) or 1 (use right half
1470 of font on output). Defaults to 0. For example, for
1471 a font whose registry is ISO8859-1, the left half
1472 (octets 0x20 - 0x7F) is the `ascii' character set, while
1473 the right half (octets 0xA0 - 0xFF) is the `latin-1'
1474 character set. With 'graphic set to 0, the octets
1475 will have their high bit cleared; with it set to 1,
1476 the octets will have their high bit set.
1477 'direction 'l2r (left-to-right) or 'r2l (right-to-left).
1479 'ccl-program A compiled CCL program used to convert a character in
1480 this charset into an index into the font. This is in
1481 addition to the 'graphic property. The CCL program
1482 is passed the octets of the character, with the high
1483 bit cleared and set depending upon whether the value
1484 of the 'graphic property is 0 or 1.
1485 'mother [UTF-2000 only] Base coded-charset.
1486 'code-min [UTF-2000 only] Minimum code-point of a base coded-charset.
1487 'code-max [UTF-2000 only] Maximum code-point of a base coded-charset.
1488 'code-offset [UTF-2000 only] Offset for a code-point of a base
