|
|
|
151 or more regular characters.
|
|
|
152
|
|
|
153 1) The old Mule implementation involves storing composite characters
|
|
|
154 in a buffer as a tag followed by all of the actual characters
|
|
|
155 used to make up the composite character. I think this is a bad
|
|
|
156 idea; it greatly complicates code that wants to handle strings
|
|
|
157 one character at a time because it has to deal with the possibility
|
|
|
158 of great big ungainly characters. It's much more reasonable to
|
|
|
159 simply store an index into a table of composite characters.
|
|
|
160
|
|
|
161 2) The current implementation only allows for 16,384 separate
|
|
|
162 composite characters over the lifetime of the XEmacs process.
|
|
|
163 This could become a potential problem if the user
|
|
|
164 edited lots of different files that use composite characters.
|
|
|
165 Due to FSF bogosity, increasing the number of allowable
|
|
|
166 composite characters under Mule would decrease the number
|
|
|
167 of possible faces that can exist. Mule already has shrunk
|
|
|
168 this to 2048, and further shrinkage would become uncomfortable.
|
|
|
169 No such problems exist in XEmacs.
|
|
|
170
|
|
|
171 Composite characters could be represented as 0x80 C1 C2 C3,
|
|
|
172 where each C[1-3] is in the range 0xA0 - 0xFF. This allows
|
|
|
173 for slightly under 2^20 (one million) composite characters
|
|
|
174 over the XEmacs process lifetime, and you only need to
|
|
|
175 increase the size of a Mule character from 19 to 21 bits.
|
|
|
176 Or you could use 0x80 C1 C2 C3 C4, allowing for about
|
|
|
177 85 million (slightly over 2^26) composite characters. */

647 'final Final byte of ISO 2022 escape sequence. Must be

648 supplied. Each combination of (DIMENSION, CHARS) defines a

649 separate namespace for final bytes. Note that ISO

650 2022 restricts the final byte to the range
|

651 0x30 - 0x7E if dimension == 1, and 0x30 - 0x5F if

652 dimension == 2. Note also that final bytes in the range

653 0x30 - 0x3F are reserved for user-defined (not official)
|

654 character sets.
|

655 'graphic 0 (use left half of font on output) or 1 (use right half
|

656 of font on output). Defaults to 0. For example, for

657 a font whose registry is ISO8859-1, the left half
|
|
|
658 (octets 0x20 - 0x7F) is the `ascii' character set, while
|
|
|
659 the right half (octets 0xA0 - 0xFF) is the `latin-1'
|
|
|
660 character set. With 'graphic set to 0, the octets

661 will have their high bit cleared; with it set to 1,

662 the octets will have their high bit set.
