       No replacement functionality in GNU SASL, use GNU Libidn instead.  Note that in  SASL,  you  most  likely
       want to use SASLprep and not bare NFKC, see gsasl_saslprep().

       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:  Return  a  newly  allocated string, that is the NFKC normalized form of  str , or NULL on
       error.
