NAME

6       stringprep_utf8_nfkc_normalize - API function
7

SYNOPSIS

9       #include <stringprep.h>
10
11       char * stringprep_utf8_nfkc_normalize(const char * str, ssize_t len);
12

ARGUMENTS

14       const char * str
15                   a UTF-8 encoded string.
16
17       ssize_t len length of str, in bytes, or -1 if str is nul-terminated.
18

DESCRIPTION

20       Converts  a  string  into  canonical form, standardizing such issues as
21       whether a character with an accent is represented as a  base  character
22       and combining accent or as a single precomposed character.
23
24       The  normalization mode is NFKC (ALL COMPOSE).  It standardizes differ‐
25       ences that do not affect the text content, such as the  above-mentioned
26       accent  representation.  It standardizes the "compatibility" characters
27       in Unicode, such as SUPERSCRIPT THREE to the standard  forms  (in  this
28       case DIGIT THREE). Formatting information may be lost but for most text
29       operations such characters should be considered the same. It returns  a
30       result with composed forms rather than a maximally decomposed form.
31

RETURN VALUE

33       a newly allocated string, that is the NFKC normalized form of str.
