5 "The " { $vocab-link "unicode" } " vocabulary and its sub-vocabularies implement support for the Unicode 14.0 character set."
7 "The Unicode character set contains most of the world's writing systems. Unicode is intended as a replacement for, and is a superset of, such legacy character sets as ASCII, Latin1, MacRoman, and so on. Unicode characters are called " { $emphasis "code points" } "; Factor's " { $link "strings" } " are sequences of code points."
9 "The Unicode character set is accompanied by several standard algorithms for common operations like encoding text in files, capitalizing a string, finding the boundaries between words, and so on."
11 "The Unicode algorithms implemented by the " { $vocab-link "unicode" } " vocabulary are:"
13 { "Case mapping" "unicode.case" }
14 { "Collation and weak comparison" "unicode.collation" }
15 { "Character classes" "unicode.categories" }
16 { "Word and grapheme breaks" "unicode.breaks" }
17 { "Unicode normalization" "unicode.normalize" }
19 "The following are mostly for internal use:"
21 { "Unicode category syntax" "unicode.categories" }
22 { "Unicode data tables" "unicode.data" }
24 { $see-also "ascii" "io.encodings" } ;
