33 Ben Wing: wrote, for 19.13 (Mule). Some category table stuff
34 loosely based on the original Mule.
35 Jareth Hein: fixed a couple of bugs in the implementation, and
36 added regex support for categories with check_category_at

1259 Implementing a general data structure that maps from arbitrary

1261 happens, it should suffice (and is usually more convenient, anyway)
1262 when dealing with characters to restrict the sorts of ranges that
1263 can be assigned values, as follows:
1266 2) All characters in a charset.
1267 3) All characters in a particular row of a charset, where a "row"
1268 means all characters with the same first byte.
1269 4) A particular character in a charset.
1271 We use char tables to generalize the 256-element vectors now

1280 5) keyboard-translate-table?

1708 A char table is a table that maps characters (or ranges of characters)

1711 loses in generality, it makes for extremely fast (constant-time)
1712 lookups, and thus is feasible for applications that do an extremely
1713 large number of lookups (e.g. scanning a buffer for a character in
1714 a particular syntax, where a lookup in the syntax table must occur
1715 once per character).
1717 When Mule support exists, the types of ranges that can be assigned
1721 -- an entire charset
1722 -- a single row in a two-octet charset
1723 -- a single character
1725 When Mule support is not present, the types of ranges that can be
1729 -- a single character
1731 To create a char table, use `make-char-table'.
1732 To modify a char table, use `put-char-table' or `remove-char-table'.
1733 To retrieve the value for a particular character, use `get-char-table'.

4426 A category table is a type of char table used for keeping track of
4427 categories. Categories are used for classifying characters for use
4428 in regexps -- you can refer to a category rather than having to use
4429 a complicated [] expression (and category lookups are significantly
4432 There are 95 different categories available, one for each printable
4433 character (including space) in the ASCII charset. Each category
4434 is designated by one such character, called a "category designator".
4435 They are specified in a regexp using the syntax "\\cX", where X is
4436 a category designator.
4438 A category table specifies, for each character, the categories that
4439 the character is in. Note that a character can be in more than one
4440 category. More specifically, a category table maps from a character
4441 to either the value nil (meaning the character is in no categories)
4442 or a 95-element bit vector, specifying for each of the 95 categories
4443 whether the character is in that category.
4445 Special Lisp functions are provided that abstract this, so you do not
4446 have to directly manipulate bit vectors.

4835 Emacs treats a sequence of word constituent characters as a single
4836 word (i.e. finds no word boundary between them) iff they belongs to
4837 the same charset. But, exceptions are allowed in the following cases.
4839 \(1) The case that characters are in different charsets is controlled
4840 by the variable `word-combining-categories'.
4842 Emacs finds no word boundary between characters of different charsets
4843 if they have categories matching some element of this list.
4845 More precisely, if an element of this list is a cons of category CAT1
4846 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4847 C2 which has CAT2, there's no word boundary between C1 and C2.
4849 For instance, to tell that ASCII characters and Latin-1 characters can
4850 form a single word, the element `(?l . ?l)' should be in this list
4851 because both characters have the category `l' (Latin characters).
4853 \(2) The case that character are in the same charset is controlled by
4854 the variable `word-separating-categories'.
4856 Emacs find a word boundary between characters of the same charset
4857 if they have categories matching some element of this list.
4859 More precisely, if an element of this list is a cons of category CAT1
4860 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4861 C2 which has CAT2, there's a word boundary between C1 and C2.
4863 For instance, to tell that there's a word boundary between Japanese
4864 Hiragana and Japanese Kanji (both are in the same charset), the
