NAME
stringprep_utf8_nfkc_normalize - normalize Unicode string
SYNOPSIS
#include <stringprep.h>
char * stringprep_utf8_nfkc_normalize(const char * str, ssize_t len);
ARGUMENTS
const char * str
a UTF-8 encoded string.
ssize_t len length of str, in bytes, or -1 if str is nul-terminated.
DESCRIPTION
Converts a string into canonical form, standardizing such issues as whether a character
with an accent is represented as a base character and combining accent or as a single pre-
composed character.
The normalization mode is NFKC (ALL COMPOSE). It standardizes differences that do not
affect the text content, such as the above-mentioned accent representation. It standard-
izes the "compatibility" characters in Unicode, such as SUPERSCRIPT THREE to the standard
forms (in this case DIGIT THREE). Formatting information may be lost but for most text
operations such characters should be considered the same. It returns a result with com-
posed forms rather than a maximally decomposed form.
RETURN VALUE
a newly allocated string, that is the NFKC normalized form of str.
