1651 or more regular characters.
1653 1) The old Mule implementation involves storing composite characters
1654 in a buffer as a tag followed by all of the actual characters
1655 used to make up the composite character. I think this is a bad
1656 idea; it greatly complicates code that wants to handle strings
1657 one character at a time because it has to deal with the possibility
1658 of great big ungainly characters. It's much more reasonable to
1659 simply store an index into a table of composite characters.
1661 2) The current implementation only allows for 16,384 separate
1662 composite characters over the lifetime of the XEmacs process.
1663 This could become a potential problem if the user
1664 edited lots of different files that use composite characters.
1665 Due to FSF bogosity, increasing the number of allowable
1666 composite characters under Mule would decrease the number
1667 of possible faces that can exist. Mule already has shrunk
1668 this to 2048, and further shrinkage would become uncomfortable.
1669 No such problems exist in XEmacs.
1671 Composite characters could be represented as 0x80 C1 C2 C3,
1672 where each C[1-3] is in the range 0xA0 - 0xFF. This allows
1673 for slightly under 2^20 (one million) composite characters
1674 over the XEmacs process lifetime, and you only need to
1675 increase the size of a Mule character from 19 to 21 bits.
1676 Or you could use 0x80 C1 C2 C3 C4, allowing for about
1677 85 million (slightly over 2^26) composite characters. */

2586 NAME is a symbol, the name by which the character set is normally referred.
2587 DOC-STRING is a string describing the character set.
2588 PROPS is a property list, describing the specific nature of the
2589 character set. Recognized properties are:
2591 'short-name Short version of the charset name (ex: Latin-1)
2592 'long-name Long version of the charset name (ex: ISO8859-1 (Latin-1))
2593 'registry A regular expression matching the font registry field for
2595 'dimension Number of octets used to index a character in this charset.
2596 Either 1 or 2. Defaults to 1.
2597 'columns Number of columns used to display a character in this charset.
2598 Only used in TTY mode. (Under X, the actual width of a
2599 character can be derived from the font used to display the
2600 characters.) If unspecified, defaults to the dimension
2601 (this is almost always the correct value).
2602 'chars Number of characters in each dimension (94 or 96).
2603 Defaults to 94. Note that if the dimension is 2, the
2604 character set thus described is 94x94 or 96x96.
2605 'final Final byte of ISO 2022 escape sequence. Must be
2606 supplied. Each combination of (DIMENSION, CHARS) defines a
2607 separate namespace for final bytes. Note that ISO
2608 2022 restricts the final byte to the range
2609 0x30 - 0x7E if dimension == 1, and 0x30 - 0x5F if
2610 dimension == 2. Note also that final bytes in the range
2611 0x30 - 0x3F are reserved for user-defined (not official)
2613 'graphic 0 (use left half of font on output) or 1 (use right half
2614 of font on output). Defaults to 0. For example, for
2615 a font whose registry is ISO8859-1, the left half
2616 (octets 0x20 - 0x7F) is the `ascii' character set, while
2617 the right half (octets 0xA0 - 0xFF) is the `latin-1'
2618 character set. With 'graphic set to 0, the octets
2619 will have their high bit cleared; with it set to 1,
2620 the octets will have their high bit set.
2621 'direction 'l2r (left-to-right) or 'r2l (right-to-left).
2623 'ccl-program A compiled CCL program used to convert a character in
2624 this charset into an index into the font. This is in
2625 addition to the 'graphic property. The CCL program
2626 is passed the octets of the character, with the high
2627 bit cleared and set depending upon whether the value
