NAME
stringprep_utf8_nfkc_normalize - API function
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 precomposed 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 standardizes 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 composed forms rather
than a maximally decomposed form.
Return value: a newly allocated string, that is the NFKC normalized
form of
str .
