154 or more regular characters.
|
|
|
155
|
|
|
156 1) The old Mule implementation involves storing composite characters
|
|
|
157 in a buffer as a tag followed by all of the actual characters
|
|
|
158 used to make up the composite character. I think this is a bad
|
|
|
159 idea; it greatly complicates code that wants to handle strings
|
|
|
160 one character at a time because it has to deal with the possibility
|
|
|
161 of great big ungainly characters. It's much more reasonable to
|
|
|
162 simply store an index into a table of composite characters.
|
|
|
163
|
|
|
164 2) The current implementation only allows for 16,384 separate
|
|
|
165 composite characters over the lifetime of the XEmacs process.
|
|
|
166 This could become a potential problem if the user
|
|
|
167 edited lots of different files that use composite characters.
|
|
|
168 Due to FSF bogosity, increasing the number of allowable
|
|
|
169 composite characters under Mule would decrease the number
|
|
|
170 of possible faces that can exist. Mule already has shrunk
|
|
|
171 this to 2048, and further shrinkage would become uncomfortable.
|
|
|
172 No such problems exist in XEmacs.
|
|
|
173
|
|
|
174 Composite characters could be represented as 0x80 C1 C2 C3,
|
|
|
175 where each C[1-3] is in the range 0xA0 - 0xFF. This allows
|
|
|
176 for slightly under 2^20 (one million) composite characters
|
|
|
177 over the XEmacs process lifetime, and you only need to
|
|
|
178 increase the size of a Mule character from 19 to 21 bits.
|
|
|
179 Or you could use 0x80 C1 C2 C3 C4, allowing for about
|
|
|
180 85 million (slightly over 2^26) composite characters. */
