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

+'graphic 0 (use left half of font on output) or 1 (use right half
+ of font on output). Defaults to 0. For example, for
+ a font whose registry is ISO8859-1, the left half
+ (octets 0x20 - 0x7F) is the `ascii' character set, while
+ the right half (octets 0xA0 - 0xFF) is the `latin-1'
+ character set. With 'graphic set to 0, the octets
+ will have their high bit cleared; with it set to 1,
+ the octets will have their high bit set.
+'direction 'l2r (left-to-right) or 'r2l (right-to-left).
+ Defaults to 'l2r.
+'ccl-program A compiled CCL program used to convert a character in
+ this charset into an index into the font. This is in
+ addition to the 'graphic property. The CCL program
+ is passed the octets of the character, with the high
+ bit cleared and set depending upon whether the value
