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 .
