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

1264 when dealing with characters to restrict the sorts of ranges that
1265 can be assigned values, as follows:
1268 2) All characters in a charset.
1269 3) All characters in a particular row of a charset, where a "row"
1270 means all characters with the same first byte.
1271 4) A particular character in a charset.
1273 We use char tables to generalize the 256-element vectors now

1276 Possible uses (all should be converted at some point):
1282 5) keyboard-translate-table?

1710 A char table is a table that maps characters (or ranges of characters)

1712 particular sorts of ranges to be assigned values. Although this
1713 loses in generality, it makes for extremely fast (constant-time)
1714 lookups, and thus is feasible for applications that do an extremely
1715 large number of lookups (e.g. scanning a buffer for a character in
1716 a particular syntax, where a lookup in the syntax table must occur
1717 once per character).
1719 When Mule support exists, the types of ranges that can be assigned
1723 -- an entire charset
1724 -- a single row in a two-octet charset
1725 -- a single character
1727 When Mule support is not present, the types of ranges that can be
1731 -- a single character
1733 To create a char table, use `make-char-table'.
1734 To modify a char table, use `put-char-table' or `remove-char-table'.
1735 To retrieve the value for a particular character, use `get-char-table'.

4376 A category table is a type of char table used for keeping track of
4377 categories. Categories are used for classifying characters for use
4378 in regexps -- you can refer to a category rather than having to use
4379 a complicated [] expression (and category lookups are significantly
4382 There are 95 different categories available, one for each printable
4383 character (including space) in the ASCII charset. Each category
4384 is designated by one such character, called a "category designator".
4385 They are specified in a regexp using the syntax "\\cX", where X is
4386 a category designator.
4388 A category table specifies, for each character, the categories that
4389 the character is in. Note that a character can be in more than one
4390 category. More specifically, a category table maps from a character
4391 to either the value nil (meaning the character is in no categories)
4392 or a 95-element bit vector, specifying for each of the 95 categories
4393 whether the character is in that category.

4782 Emacs treats a sequence of word constituent characters as a single
4783 word (i.e. finds no word boundary between them) iff they belongs to
4784 the same charset. But, exceptions are allowed in the following cases.
4786 \(1) The case that characters are in different charsets is controlled
4787 by the variable `word-combining-categories'.
4789 Emacs finds no word boundary between characters of different charsets
4790 if they have categories matching some element of this list.
4792 More precisely, if an element of this list is a cons of category CAT1
4793 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4794 C2 which has CAT2, there's no word boundary between C1 and C2.
4796 For instance, to tell that ASCII characters and Latin-1 characters can
4797 form a single word, the element `(?l . ?l)' should be in this list
4798 because both characters have the category `l' (Latin characters).
4800 \(2) The case that character are in the same charset is controlled by
4801 the variable `word-separating-categories'.
4803 Emacs find a word boundary between characters of the same charset
4804 if they have categories matching some element of this list.
4806 More precisely, if an element of this list is a cons of category CAT1
4807 and CAT2, and a multibyte character C1 which has CAT1 is followed by
4808 C2 which has CAT2, there's a word boundary between C1 and C2.
4810 For instance, to tell that there's a word boundary between Japanese
4811 Hiragana and Japanese Kanji (both are in the same charset), the
4812 element `(?H . ?C) should be in this list.
