+ Implementing a general data structure that maps from arbitrary
+ ranges of numbers to values is tricky to do efficiently. As it
+ happens, it should suffice (and is usually more convenient, anyway)
+ when dealing with characters to restrict the sorts of ranges that
+ can be assigned values, as follows:
-#ifdef HAVE_CHISE
-EXFUN (Fload_char_attribute_table, 1);
+ 1) All characters.
+ 2) All characters in a charset.
+ 3) All characters in a particular row of a charset, where a "row"
+ means all characters with the same first byte.
+ 4) A particular character in a charset.

+ We use char tables to generalize the 256-element vectors now
+ littering the Emacs code.

+A char table is a table that maps characters (or ranges of characters)
+to values. Char tables are specialized for characters, only allowing
+particular sorts of ranges to be assigned values. Although this
+loses in generality, it makes for extremely fast (constant-time)
+lookups, and thus is feasible for applications that do an extremely
+large number of lookups (e.g. scanning a buffer for a character in
+a particular syntax, where a lookup in the syntax table must occur
+once per character).
- cte = alloc_lcrecord_type (Lisp_Uint16_Byte_Table,
- &lrecord_uint16_byte_table);
+When Mule support exists, the types of ranges that can be assigned
+values are
- for (i = 0; i < 256; i++)
- cte->property[i] = initval;
+-- all characters (represented by t)
+-- an entire charset
+-- a single row in a two-octet charset (represented by a vector of two
+ elements: a two-octet charset and a row number; the row must be an
+ integer, not a character)

+When Mule support is not present, the types of ranges that can be

-A char table is a table that maps characters (or ranges of characters)
-to values. Char tables are specialized for characters, only allowing
-particular sorts of ranges to be assigned values. Although this
-loses in generality, it makes for extremely fast (constant-time)
-lookups, and thus is feasible for applications that do an extremely
-large number of lookups (e.g. scanning a buffer for a character in
-a particular syntax, where a lookup in the syntax table must occur
-once per character).
-
-When Mule support exists, the types of ranges that can be assigned
-values are
-
--- all characters
--- an entire charset
--- a single row in a two-octet charset
--- a single character
-
-When Mule support is not present, the types of ranges that can be
-assigned values are
-
--- all characters
--- a single character
-
-To create a char table, use `make-char-table'.
-To modify a char table, use `put-char-table' or `remove-char-table'.
-To retrieve the value for a particular character, use `get-char-table'.
-See also `map-char-table', `clear-char-table', `copy-char-table',
-`valid-char-table-type-p', `char-table-type-list',
-`valid-char-table-value-p', and `check-char-table-value'.
