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 .
