+   This function's result is locale dependent.  Unlike memcasecmp(), it works
+   correctly in multibyte locales and also handles Turkish i / dotless i.
+   Unlike ulc_casecmp(), it does not handle the German sharp s and the Greek
+   final sigma.  Like memcoll() and ulc_casecoll(), it uses collation order.
+
+   Return a negative number if S1 < S2, a positive number if S1 > S2, 0 if
+   S1 and S2 have the same contents, or an unspecified value if there is an
+   error.
+   Set errno to an error number if there is an error, and to zero otherwise.
