"The " { $vocab-link "unicode.normalize" "unicode.normalize" } " vocabulary defines words for normalizing Unicode strings. In Unicode, it is often possible to have multiple sequences of characters which really represent exactly the same thing. For example, to represent e with an acute accent above, there are two possible strings: \"e\\u000301\" (the e character, followed by the combining acute accent character) and \"\\u0000e9\" (a single character, e with an acute accent). There are four normalization forms: NFD, NFC, NFKD, and NFKC. Basically, in NFD and NFKD, everything is expanded, whereas in NFC and NFKC, everything is contracted. In NFKD and NFKC, more things are expanded and contracted. This is a process which loses some information, so it should be done only with care. Most of the world uses NFC to communicate, but for many purposes, NFD/NFKD is easier to process. For more information, see Unicode Standard Annex #15 and section 3 of the Unicode standard."

"Unicode is a set of characters, or " { $emphasis "code points" } " covering what's used in most world writing systems. Any Factor string can hold any of these code points transparently; a factor string is a sequence of Unicode code points. Unicode is accompanied by several standard algorithms for common operations like encoding in files, capitalizing a string, finding the boundaries between words, etc. When a programmer is faced with a string manipulation problem, where the string represents human language, a Unicode algorithm is often much better than the naive one. This is not in terms of efficiency, but rather internationalization. Even English text that remains in ASCII is better served by the Unicode collation algorithm than a naive algorithm.
