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

1266 when dealing with characters to restrict the sorts of ranges that
1267 can be assigned values, as follows:
1270 2) All characters in a charset.
1271 3) All characters in a particular row of a charset, where a "row"
1272 means all characters with the same first byte.
1273 4) A particular character in a charset.
1275 We use char tables to generalize the 256-element vectors now

1284 5) keyboard-translate-table?

1712 A char table is a table that maps characters (or ranges of characters)

1715 loses in generality, it makes for extremely fast (constant-time)
1716 lookups, and thus is feasible for applications that do an extremely
1717 large number of lookups (e.g. scanning a buffer for a character in
1718 a particular syntax, where a lookup in the syntax table must occur
1719 once per character).
1721 When Mule support exists, the types of ranges that can be assigned
1724 -- all characters (represented by t)
1725 -- an entire charset
1726 -- a single row in a two-octet charset (represented by a vector of two
1727 elements: a two-octet charset and a row number; the row must be an
1728 integer, not a character)
1729 -- a single character
1731 When Mule support is not present, the types of ranges that can be

1738 To modify a char table, use `put-char-table' or `remove-char-table'.
1739 To retrieve the value for a particular character, use `get-char-table'.

4467 A category table is a type of char table used for keeping track of
4468 categories. Categories are used for classifying characters for use
4469 in regexps -- you can refer to a category rather than having to use
4470 a complicated [] expression (and category lookups are significantly
4473 There are 95 different categories available, one for each printable
4474 character (including space) in the ASCII charset. Each category
4475 is designated by one such character, called a "category designator".
4476 They are specified in a regexp using the syntax "\\cX", where X is
4477 a category designator.
4479 A category table specifies, for each character, the categories that
4480 the character is in. Note that a character can be in more than one
4481 category. More specifically, a category table maps from a character
4482 to either the value nil (meaning the character is in no categories)
4483 or a 95-element bit vector, specifying for each of the 95 categories
4484 whether the character is in that category.
4486 Special Lisp functions are provided that abstract this, so you do not
4487 have to directly manipulate bit vectors.
